The answer is, 222
- Answer c
The pattern is, *1 + 2, *1.5 -4, *2 + 6, *2.5 -8, *3 + 10,..
The answer is, 1163.5
Directions (Q. 6 – 10):
- Answer b
(800/40) = x – 366
20 = x – 366
X = 20 + 366 = 386
X = 390
- Answer a
(4/7)*(8/17)*(31/65)*325 = x
X = (4/8)*(8/16)*(32/65)*325
X = 40
- Answer d
14 × 6 + 752 × 13 = x
X = 84 + 73125
X = 73209
X = 73210
- Answer c
626 – 362 ÷ ((10/100)*82) = x
626 – 362 ÷ 8.2 = x
626 – (362/8) = x
X = 626 – 45 = 581
X = 580
- Answer b
(14)2 – (13)2 + (4325 + 80) ÷? = 225
196 – 169 + (4405/x) = 225
(4405/x) = 225 – 196 + 169
(4405/x) = 198
x = 4405/198
x = 4400/200
x = 22
- Answer a
Let Rajiv’s monthly salary be x,
According to the question,
X*(35/100)*(65/100) = 22750
X = 22750*(100/65)*(100/35)
X = 100000
- Answer d
Total Quantity = 84 litres
The ratio of milk to water= 7: 5
Milk= 49 litres, Water= 35 litres
According to the question,
49/(35+x) = 7/8
56 = 35+x
X= 21 litres
So 21 litres of water should be added.
- Answer c
The share of A, B and C = [(25000*3) + (35000*9)] : [35000*12] : [45000*12]
= > 390000: 420000: 540000
= > 13: 14: 18
14’s = 24500
1’s = 1750
Total profit = 45’s = 1750*45 = 78750
- Answer c
A’s whole work,
(3/4)*A’s work = 12
A’s work = 16 days
(A+ B)’s work = 12 days
B’s one day work = (1/12) – (1/16) = 1/48
B’s whole work = 48 days
(B : C)’s efficiency = 1 : 2
(B : C)’s day ratio = 2:1
So, 2’s = 48
1’s = 24
C’s whole work = 24 days
- Answer c
The ratio of B’s age six years hence to C’s present age is 3:2(3x, 2x)
Present ages of B to C = 3x-6, 2x
Present ages of A to C = 2 : 1(2x, x)
Present ages of A, B and C = 4x, 3x-6, 2x
B = A – 15
A – B = 15
4x – (3x-6) = 15
4x – 3x + 6 = 15
X = 9
B’s age 4 years ago = 3x – 6 – 4 = 27 – 10 = 17 years

Answer a
Total marks scored by Ram = 117 + 90 + 196 + 126 + 81 + 57 = 667
- Answer d
Required % =[(178+111)/(156+135)] = (289/291)*100 = 99.31 = 100 %
- Answer c
Total marks scored by all the students in Maths,
= > 196 + 178 + 150 + 188 + 156 = 868
Total marks scored by all the students in Chemistry,
= > 90 + 84 + 66 + 102 + 108 = 450
Required ratio = 868: 450 = 434: 225
- Answer e
Ram = 661
Akil = 578
Ragu = 572
Jeyashree = 660
Bharathi = 655
Ram get a highest total marks.
- Answer d
Total marks scored by Akil in all the subject is,
= > 93 + 84 + 178 + 111 + 79 + 33 = 578
The total marks scored by Ragu in all the subject is,
= > 111 + 66 + 150 + 123 + 68 + 54= 572
Required % = [(578-572)/572]*100 = 1.048 % = 1 %
