Answers :
1) Answer: D
According to the question,
(15 % – 10 %) of salary = 4000
5 % of salary = 4000
Total salary = 4000*(100/5) = Rs. 80000 = 100 %
Savings % = (20000/80000)*100 = 25 %
Total salary (100 %) = Expense (75 %) + Savings (25 %)
75 % = (15 % + 20 % + 10 % + X %)
X % = 75 % – 45 % = 30 %
2) Answer: D
Let, total income of Raghav be Rs. P
(a)
(100 – 20)/100 x (100 – 10)/100 x (100 – 25)/100 x (100 – 20)/100 x P = 10800
=> 80/100 x 90/100 x 75/100 x 80/100 x P = 10800
=> P = 10800 x 100/80 x 100/90 x 100/75 x 100/80
=> P = Rs.25000
Amount spent by Raghav on entertainment
= 80/100 x 90/100 x 25/100 x 25000
= Rs.4500 = 4500
=> Satisfies the given condition.
(b)
(100 – 20)/100 x (100 – 10)/100 x (100 – 25)/100 x (100 – 20)/100 x P = 13500
=> 80/100 x 90/100 x 75/100 x 80/100 x P = 13500
=> P = 13500 x 100/80 x 100/90 x 100/75 x 100/80
=> P = Rs.31250
Amount spent by Raghav on entertainment
= 80/100 x 90/100 x 25/100 x 31250
= Rs.5625 = 5625
=> Satisfies the given condition.
(c)
(100 – 20)/100 x (100 – 10)/100 x (100 – 25)/100 x (100 – 20)/100 x P = 18900
=> 80/100 x 90/100 x 75/100 x 80/100 x P = 18900
=> P = 18900 x 100/80 x 100/90 x 100/75 x 100/80
=> P = Rs.43750
Amount spent by Raghav on entertainment
= 80/100 x 90/100 x 25/100 x 43750
= Rs.7875 = 7875
=> Satisfies the given condition
3) Answer: C
Let Blue balls = x
Red balls = x * 120/100 = 6x/5
x* 60/100 = 40/100 *Orange balls
Orange balls = 3x/2
Yellow balls = 3x/5
3x/2 – 6x/5 = 15
15x – 12x = 150
x = 50
Total number of balls = x + 6x/5 + 3x/2 + 3x/5
= 50+60+75+30
= 215
4) Answer: E
Number of red balls = x
Number of blue balls = 100 – x
x * 120/100 + (100 – x + 9) = 100 * 123/100
6x/5 + 109 – x = 123
6x + 545 – 5x = 123 * 5
x = 70
Number of blue balls = 100 – 70 = 30
Required ratio = 7: 3
5) Answer: C
Let x be the total mark in that exam, then
Rajeev’s score = 412 marks, Sanjay’s score = 75 % = Rajeev’s score + 8
Sanjay = 412 + 8 = 420 = 75 % of total marks
(75/100)* x = 420
x = 420 * (100/75) = 560
Minimum passing marks = 35 % of total marks
= > (35/100)* 560 = 196
Rajeev scored 216 marks more than the passing marks.
6) Answer: D
Total costs of all the properties = 18000 + 30000 + 400000 = 448000
New worth of the Renu properties
= ((18000 * 110/100) + (30000 * 95/100) + (400000 * 80/100))
= 19800 + 28500 + 320000
= 368300
Required percentage = (448000 – 368300)/448000 * 100
= 17.8% decreases
7) Answer: A
Number of employees in B = x
Number of employees in A = x * 120/100 = 6x/5
Number of employees in C = 6x/5 * 130/100 = 39x/25
Female in A = 6x/5 * 12/25 = 72x/125
Female in B = 9/20 * x = 9x/20
Female in C = 39x/25 * 2/5 = 78x/125
Required percentage = (72x/125 + 9x/20 + 78x/125)/(x + 6x/5 + 39x/25) * 100
= (288x + 225x + 312x)/500 * 25/(25x + 30x + 39x) * 100
= 44%
8) Answer: E
Number of students from B = x
Number of students from A = x * 150/100 = 3x/2
Number of students from D = y
Number of students from C = y * 160/100 = 8y/5
x – y = 40 ———-(1)
3x/2 + 8y/5 = 123 * 2 = 246
15x + 16y = 2460 ——–(2)
(2) – (1) * 15
31y = 2460 – 600
y = 60
x = 40 + 60 = 100
Number of students from A = 150/100 * 100 = 150
Number of students from C = 60 * 160/100 = 96
Required total = (96 + 150 + 100 + 60) = 406
9) Answer: C
Let number of students in section I, II and III = 400x, 500x and 700x respectively.
So,
Boys in section III = 700x × 13/25 = 364x
Girls in section III = 700 × 12/25 = 336x
In section I, number of boys = 400x × 40/100 = 160x
So, the number of girls is = 400x – 160x = 240x
Let number of girls in section II = x
So, according to the question,
= x/3 + x = 500x
= 4x/3 = 500x
= x = 375x
So, number of boys in section II = 500x – 375x = 125x
Now, the total number of boys in all sections = 364x + 160x + 125x = 649x
And the total number of girls in all sections = 336x + 240x + 375x = 951x
So, the required percentage = (951x – 649x)/951x × 100
= 302x/951x × 100 ≈ 32%less
10) Answer: D
Let the number of black marbles in bag and pink 7a and 6a respectively.
Number of yellow marbles in bag = 6a + 12
Number of green marbles in Bag = (100% – 18.75%) of (6a + 12)
= 13/16 x (6a + 12)
According to the question,
7a + (13/16) x (6a + 12)= 936
112a + 78a + 156 = 936 x 16
190a = 14820
So, value of a = 78
Total balls in the bag = 7 x 78 + 6 x 78 + (6 x 78 + 12) + 13/16 x (6×78 + 12)
= 546 + 468 + 480 + 390
= 1884
