Answers :
1) Answer: B
A’s age after 4 years = 3x
B’s age after 4 years = 2x
Present age of B = 2x – 4
C’s present age – 5 = 2x – 4 – 8
C’s present age = 2x – 7
A + B + C = 32(1/3) * 3 = 97
3x – 4 + 2x – 4 + 2x – 7 = 97
7x = 112
x = 16
A’s present age = 3 * 16 – 4 = 44 years
2) Answer: C
A = 6(B – 2)
A = 6B – 12
6B – A = 12 —-(i)
A + 4 = 4(B + 4)
A – 4B = 12 —-(ii)
Solving equation i and ii we get,
A = 60 years and B = 12 years
So after 6 yrs, age of B will be 12 + 6 = 18 years.
3) Answer: A
Present age of Karthick = 20 years
Present age of Ram = 20 + 6 = 26 years
Anu’s age = 26 + 4 = 30 years
Present age of France = 30 * 4/5 = 24 years
Required percentage = 20/24 * 100 = 83%
4) Answer: B
(7x + 4)/(5x + 4) = 15/11
75x + 60 = 77x + 44
2x = 16
X = 8
Arul age 5 years ago = (7 * 8) – 5 = 51
Arun age 5 years ago = (5 * 8) – 5 = 35
Difference = 51 – 35 = 16 years
5) Answer: B
Ratio of the ages of A, B, C, D and E = 12: 15: 18: 12: 8
18x + 12x = 60
30x = 60
x = 2
Required average = ((12 + 15 + 18 + 12 + 8) * 2)/5
= 26 years
6) Answer: C
A = 4x and B = 5x
C = 5x – 2 and D = 41 – 4x
Given, (5x + 5x – 2 + 41 – 4x)/3 = 21
=> x = 4
Required difference = D – C = 41 – 4x – 5x + 2 = 7
7) Answer: D
The ratio of present ages of Ganesh and Prabha = 3: 2 (3x, 2x)
Present age of Prabha = The age of Ganesh, 8 years ago
2x = 3x – 8
x = 8
Present age of Ganesh and Prabha = 24 and 16 years
Required Sum = 24 + 16 + 10 = 50 years
8) Answer: A
The ratio of present age of A and B = 5: 7 (5x, 7x)
After 5 years, the ratio will be = 3: 4
(5x + 5) / (7x + 5) = ¾
20x + 20 = 21x + 15
x = 5
Present ages of A and B is 25 years and 35 years respectively
Required difference = 35 – 25 = 10 years
9) Answer: C
Satish = 7x and Raju = 6x
Anu = 6x – 4 and Sweta + 7x = 54
Sweta = 54 – 7x
(6x + 6x – 4 + 54 – 7x)/3 = 23 1/3
=> x = 4
Swetha = 54 – 7x = 26 years
Anu = 6x – 4 = 20 years
Required difference = 26 – 20 = 6 years
10) Answer: C
David – 10 + Hari – 10 + Kani – 10 = 34 * 3
David + Hari + Kani = 132 years
Hari + 6 + Kani + 6 = 53 * 2
Hari + Kani = 94
David = 132 – 94 = 38 years

4A – 12=3B – 9
4A – 3B=3
((B + 4) + (C + 4))/2=40
B + C=72
A’s age after 9 years=72/2=36 years
A’s present age=36 – 9=27 years
4 * 27 – 3B=3
B=35 years
C=72 – 35=37 years
12) Answer: E
A + B + C + D=42 * 4=168
B + C + D=28 * 3=84
A + B=144
A=168 – 84 = 84 years
B =144 – 84 = 60 years
C + D =168 – (84 + 60) = 24 years
After 10 years B’s age=60 + 10=70 years
C’s age after 10 years=70 * 3/70=30 years
Present age of C=30 – 10=20 years
D =24 – 20 = 4 years.
13) Answer: E
(A – 5)/(B – 5) = 2/1
A – 5 = 2B – 10
A – 2B = -5
A = B + 20
B + 20 – 2B=-5
B = 25
A = 25 + 20=45
C = 120/100 * (45 + 25)
= 84 years
After 8 years C’s age = 84 + 8=92 years
14) Answer: B

Father’s age = 7x
Son’s age = 3x
Five years age, Father’s age = 7x-5
Son’s age = 3x-5
(7x – 5)/(3x – 5) = 5/2
14x – 10 = 15x – 25
x = 15
Son’s present age = 15 * 3=45 years
After 10years, the son’s age = 55 years
15) Answer: A
A=120B/100
A=6/5 * B

Shon=42 years
Sunil=2/3 * 42=28
Sam=78 – 28=50 years
17) Answer: A
(4x + 6 + 12)/(5x + 6 + 12) = 7/8
(4x + 18) * 8 = (5x + 18) * 7
32x + 144 = 35x + 126
3x = 18
x = 6 years
Preset age ratio of Shon to Sania= (4 * 6 + 6):(5 * 6 + 6)
= 30:36
=5:6
18) Answer: C
Three years hence, the ratio of Karthi and Janvi = 7:5(7x, 5x)
Present age of Karthi and Janvi = 7x – 3, 5x – 3
According to the question,
7x – 1 = 2*(5x – 8)
7x – 1 = 10x – 16
3x = 15
x = 5
The present age of Karthi = 7x – 3 = 35 – 3 = 32 years
19) Answer: C
Ovi’s present age = 4x
Kavi’s present age = 5x
Pooja = 60/100 * 5x = 3x
Sum of the ages of Ovi, Kavi and Pooja = 24 * 3 = 72
4x + 5x + 3x = 72
x = 6 years
Sum of the present age of Pooja and Ovi = 4x + 3x = 7x
= 7 * 6 = 42 years
20) Answer: A
The ratio of ages of A and B, 5 years ago = 4: 5 (4x, 5x)
(4x + 10)/(5x + 10) = 6/7
30x + 60 = 28x + 70
2x = 10
x = 5
A’s age after 20 years = 4 * 5 + 5 + 20 = 45
B’s age after 20 years = 5 * 5 + 5 + 20 = 50
Difference between A and B = 5 years

Answers :
21) Answer: B
Let the age of Sachin = x
And the age of his father = 3x
So, according to the question,
(x + 8)/(3x + 8) = 3/7
7x + 56 = 9x + 24
9x – 7x = 56 – 24
2x = 32
x = 16
So, the age of Sachin before 7 year = 16 – 7 = 9 year
And the age of his father before 7 year = (16 × 3) – 7 = 41 year
Hence, the required answer = 9 : 41.
22) Answer: C
Let present ages of Rahul and Raj are ‘3x’ years and ‘4x’ years, respectively.
So,
(4x + 2) = (3x + 2) * (130/100)
40x + 20 = 39x + 26
x = 6
Rahul’s present age = 3 * 6 = 18 years
Raj’s present age = 4 * 6 = 24 years
Let after ‘t’ years Raj’s age will be 24% more than Rahul’s age.
So,
(24 + t) = (18 + t) * (124/100)
600 + 25t = 558 + 31t
t = 7
So, after 7 years, Raj’s age will 24% more than Rahul’s age.
23) Answer: B
(4x – 6) * (7x – 6) = 648
28x2 – 24x – 42x + 36 = 648
28x2 – 66x + 36 = 648
14x2 – 33x + 18 = 324
14x2 – 33x + 18 – 324 = 0
14x2 – 33x – 306 = 0
14x2 – 84x + 51x – 306 = 0
14x (x – 6) + 51(x – 6)= 0
(14x + 51) (x – 6) = 0
x = 6
Present age of Dhoni = 6 * 6 – 6 = 36 – 6 = 30 years
24) Answer: D
Vani + Kani + veni = 41 * 3 = 123
Present age of Kani = 5x + 6
Present age of Vani = 6x + 6
(5x + 6 + 4) = (6x + 6 – 2)
x = 6
Present age of Kani = 5 * 6 + 6 = 36 years
Present age of Vani = 6 * 6 + 6 = 42 years
Present age of Veni = 123 – 36 – 42 = 45
Veni age after 5 years = 45 + 5 = 50 years
25) Answer: B
Sankar = 23 / 1.15 = 20 years
Sanu = 20 * 5 / 4 = 25 years
Amol = 25 + 5 = 30 years
Required ratio = Sanu: Amol
= 20: 30 = 2: 3
26) Answer: B
Leela + Nila + Kani = 27 * 3 = 81
Nila + 9 = 3x
Kani + 9 = 4x
Leela – Kani = 9
Leela – (4x – 9) = 9
Leela = 9 + 4x – 9 = 4x
3x – 9 + 4x – 9 + 4x = 81
11x = 99
x = 9
Sum of the ages of Leela and Nila = 4 * 9 + (3 * 9 – 9)
= 54
27) Answer: B
Ram = 15x and Ravi = 13x
Sanam = 3 * 23 – 28x = 69 – 28x
Rio = 4 * 21 – 3 * 23 = 15 years
Sanam = 15 – 2 = 13 years
=> 69 – 28x = 13
=> x = 2
Ram = 15x = 30 years
Required ratio = Ram: Rio = 30: 15 = 2: 1
28) Answer: A
Let the present age of Raman = x years
And the present age of Kamal = y years
Now, x = 3y
So, according to the question,
(x + 6) = 4 × (y – 6)
x + 6 = 4y – 24
Put the value of x,
3y + 6 = 4y – 24
y = 30
So, the present age of Kamal = 30 years
And the present age of Raman = 3 × 30 = 90 years
This, the average age of both = (30 + 90)/2 = 60 years
29) Answer: D
Let Q’s present age = ‘x’ years
So, P’s present age = (x + 7) years
And R’s present age = (2x – 5) years
From the question:
2x – 5 – x – 7 = 13
x = 25
P’s present age = 25 + 7 = 32 years
P’s age after 8 years = 32 + 8 = 40 years
R’s present age = 2 * 25 – 5 = 45 years
R’s age after 8 years = 45 + 8 = 53 years
Required percentage = (53/40) * 100 = 132.5%
30) Answer: D
Let Q’s present age = ‘x’ years
So, R’s present age = 140% of ‘x’ = (7x/5) years
Let P’s present age = ‘y’ years
So,
y = 3 * [(7x/5) – x]
y = 3 * 2x/5
5y = 6x
y/x = 6/5
So, ratio of P’s present age to Q’s present age = 6: 5

Answers :
31) Answer: B
Anil + Mathavi + Merlin = 26 * 3 = 78
Mathavi = 2 * (Merlin – 6)
Anil – Mathavi = 12
Anil = 12 + 2Merlin – 12
Merlin + 2Merlin – 12 + 2Merlin = 78
5 Merlin = 90
Merlin = 18 years
32) Answer: C
The ratio of the ages of Vishva, Shalini and Shamala = 7:4:5
7x – 5x = 36
x = 18
Required average = (16 * 18)/3
= 96 years
33) Answer: B
Arul + Karan + Saran = 30 * 3 = 90
Arul – Saran = 12
Arul = 7x – 6
Karan = 6x – 6
Saran = 7x – 6 – 12
7x – 6 + 6x – 6 + 7x – 18 = 90
20x = 120
x = 6
Present age of Karan = 36 – 6 = 30 years
34) Answer: D
Let the age of P = x. Age of P and Q = 70
Age of Q = 70 – x
(x – 4): (70 – x + 4) = 3: 4
=> x = 34
Required ratio = (x + 6): (70 – x – 6)
= 40: 30 = 4: 3
35) Answer: B
Let present age of A = a, present age of B =b
It is given that, a+5+b+5=60
a+b=50
It is also given that,
a-4/b+4 = 9/16
16a-64= 9b+36
16a-9b =100
By solving the above equations we get, a=22, b=28
Present age of B=28 years
36) Answer: D
Present age of Sam = x
=> Age of Sam 5 years ago = x – 5
Age of Naren 2 years ago = 4x – 20
Present age of Naren = 4x – 20 + 2 = 4x – 18
4x – 18 = 250/100 * x
=> x = 12 = Age of Sam
37) Answer: D
S = 7x + 8
F = 6x + 8
7x + 8 – 6 = 75/100 * (6x + 8 + 8)
28x + 8 = 18x + 48
x = 4
Sureka = 7 * 4 + 8 = 36
Francis = 6 * 4 + 8 = 32
Sureka + Francis + Dev = 32 * 3 = 96
Dev = 96 – 36 – 32 = 28
38) Answer: C
Let P be the present age of Pinky, B be the present age of Blacky and W be the present age of Whitey
P = 2x – 8
B = 3x – 8
P – 4 = B/2
2P – 8 = B
2 * (2x – 8) – 8 = 3x – 8
4x – 16 – 8 = 3x – 8
x = 16
P = 32 – 8 = 24
B = 48 – 8 = 40
W = (24 + 40) * 125/100 = 80
Required answer = 80 + 5 = 85 years
39) Answer: B
Amol = 4x and Sanu = 5x
Sanam = 5 + 5x
Sanam after 5 years = 5 + 5x + 5 = 5x + 10
Sam after 5 years = 6/7 * (5x + 10) = 30x/7 + 60/7
Sam’s present age = 30x/7 + 60/7 – 5 = 30x/7 + 25/7
4x + 5x + 5x + 5 + 30x/7 + 25/7 = 25 * 4
=> 128x = 640
=> x = 5
Sanu = 5x = 25 years
40) Answer: B
Rani = 4x
Vani = 5x
Sana = [4/3 * (5x + 5)] – 5 = 20x/3 + 20/3 – 5
Sana – Rani = 15
(20x/3 + 20/3 – 5) – 4x = 15
20x – 12x = 15*3 – 5
20x – 12x = 40
x =5
Vani = 5*5 = 25
Sana = 4/3 * (5 * 5 + 5) – 5 = 35
Required average = (25 + 35)/2 = 30 years

Answers :
41) Answer: C
Present age of Ganga = 13x – 10
Present age of Senthil = 15x – 10
(13x – 10) + (15x – 10) = 18 * 2
=> x = 2
Ganga’s age = 16 years
Age of Saravanan = 9/8 * 16 = 18 years
42) Answer: B
Let present age of A =a, B=b, C=c
It is given that,
(a-10)=(b-4)
(a-b) =6
Age of C after 7 years
c+7 =15
Present age of C =15-7 =8
Average age of them =16 years
Total age of them = 16*3 =48years
a+ (a-6)+8 =48
2a -6 = 40
a=23years
Required sum = 23+3 + 8+3 = 37 years
43) Answer: D
Let present age of A =7x
After 8 years age of A = 128.56% of 7x = 9x
7x+8 =9x
x=4
Present age of A =7x =28 years
Age of B after 7 years = 140% of (28+7) = 49
Present age of B = 49 – 7 =42 years
Age of B before 2 years = 40
Age of C before 2 years = (40/5) * 6=48 years
Present age of C =50years
44) Answer: D
Total age of (A + B + C) 4 years ago = 48 x 3 = 144
Total of present age of (A + B + C) = 144 + 12 = 156
But, according to the question (A + B) after 6 years = 100
So, sum of present age of (A + B) = 100 – 12 = 88 years
Thus, the present age of C = 156 – 88 = 68 years.
45) Answer: E
5 years hence, the ratio of age of Anusha and Kavin = 3: 4 (3x, 4x)
8 years ago, the ratio of age of Anusha and Kavin = 2: 7
According to the question,
(3x – 13)/(4x – 13) = (2/7)
21x – 91 = 8x – 26
13x = 65
x = 5
The age of Kavin, 10 years hence = 4x + 5 = 25 years
46) Answer: D
(3x + 5)/(2x – 2) = 2/1
4x – 4 = 3x + 5
x = 9
A’s age = 3 * 9 = 27 years
B’s age = 2 * 9 = 18 years
Required average = (27 + 18 + 20)/2 = 32.5 years
47) Answer: A
5x – 4x = 9 years
x = 9
Anusha’s age after 6 years = 4 * 9 = 36 years
Present age of Anusha = 36 – 6 = 30 years
Present age of Ravi = 4/3 * 30 = 40 years
Ravi’s age after 5 years = 40 + 5 = 45 years
48) Answer: B
Siva’s present age = 44 – 9 = 35 years
Sara’s present age = 35 – 2 = 33 years
From the ratio = 9: 11, we get Divya’s age = 27 years
Present age of Divya’s mother = 27 + 26 = 53 years
49) Answer: D
Current age of Nakul = x years
Current age of Naren = 1.1x years
1.1x – x = 3
=> x = 30 years = Age of Nakul
50) Answer: B
Sum of ages of all students = 18 x (k – 14) = 18k – 252
When teacher is included, sum of ages of all = 19 x (k – 14 + 1) = 19k – 247
According to question
(19k – 247) – (18k – 252) = 53
k = 53 – 5 = 48
Required value = (48 – 10.5) % of 7500 = 2812.5

Answers :
51) Answer: D
Present age of Sam = x
=> Age of Sam 6 years ago = x – 5
Age of Naren 2 years ago = 4x – 20
Present age of Naren = 4x – 20 + 2 = 4x – 18
4x – 18 = 250/100 * x
=> x = 12 = Age of Sam
52) Answer: D
Let the age of P = x. Age of P and Q = 70
Age of Q = 70 – x
(x – 4): (70 – x + 4) = 3: 4
=> x = 34
Required ratio = (x + 6): (70 – x – 6)
= 40: 30 = 4: 3
53) Answer: B
Anil + Mathavi + Merlin = 26 * 3 = 78
Mathavi = 2 * (Merlin – 6)
Anil – Mathavi = 12
Anil = 12 + 2Merlin – 12
Merlin + 2Merlin – 12 + 2Merlin = 78
5 Merlin = 90
Merlin = 18 years
54) Answer: E
M + D = 51—–(1)
M – 6 = 12 * (D – 6)
M – 6 = 12D – 72
12D – M = 66—–(2)
13D = 117
D = 9
M = 51 – 9 = 42
F = 42 * 15/14 = 45
Difference = 45 – 9 = 36 years
55) Answer: E
Som = 125/100 * Ramya
Som/Ramya = 5/4
(5K + 4K) * 100/300 = Yuvi
Yuvi = 3k
Required ratio = 3K:4K:5K
= 3:4:5
56) Answer: B
M + 4 = 5(D + 4)
M + 4 = 5D + 20
M – 5D = 16 —–(1)
(M – 4)/(D – 4) = 6/1
6D – 24 = M – 4
6D – M = 20 ——-(2)
D = 36
57) Answer: E
Amala + Vimala = 28 * 2 = 56——(1)
(Amala + 12)/(Vimala – 8) = 3/2
3Vimala – 24 = 2Amala + 24

We can’t find the answer
59) Answer: D
5 years ago, their average age is 23
therefore total age = 23*2 = 46
present age of Chinnu and Nani = 46+5+5 = 56
Chinnu age = 15/28*56 = 30
after 10 years = 30+10 = 40 years
60) Answer: B
Present age of son = x
Present age of father = 200/100 * x = 2x
(x – 10)/(2x – 10) = 100/300
2x – 10 = 3x – 30
x = 20
Present age of father = 2 * 20 = 40
Required ratio = (40 + 15):(20 + 15)
= 55:35
= 11:7
