Answers :
1) Answer: D
Male IT employees = 80 * ¾ = 60
Female IT employees = 80 * ¼ = 20
Male HR employees = 2/3 * 60 = 40
Female HR employees = 1/3 * 60 = 20
Male employees in marketing = 40 + 20 = 60
Female employees in marketing = 40
Male employees in sales = 40/2 = 20
Female employees in sales = 40/2 = 20
Required ratio = (60 + 40 + 60 + 20):(20 + 20 + 40 + 20)
= 180:100
=9:5
2) Answer: C
CP of mobile = y
CP of laptop =3y
Total amount paid by Ram =(x*3y)+(6 * y) = 3xy + 6y
Total amount paid by Rahul = (6 * 3y) + (x * y) = 18y + xy
Amount Difference= (18y+xy) – (3xy + 6y)
= 12y – 2xy
(12y-2xy) = (40/100)(3xy+6y)
60y – 10xy = 6xy + 12y
48y = 16xy
x = 3
3) Answer: D
Number of balls in A = 4x
Number of balls in B = 5x
Number of balls in D = 5x – 4
Number of balls in C = ¾ * (5x – 4)
(4x + 5x + 5x – 4 + (15x – 12)/4)/4 = 87
14x + 15x/4 = 87 * 4 + 7
71x = 1420
x = 20
Number of balls in A = 20 * 4 = 80
4) Answer: D
Number of male employees in A = x
Number of female employees in A = x * 150/100 = 3x/2
Total number of employees in A = x + 3x/2 = 5x/2
Number of male employees in B = y
Number of female employees in B = 2y
Total number of employees in B = 3y
5x/2 – 3y = 120
5x – 6y = 240
5x = 240 + 6y
We cannot find the answer.
5) Answer: A
Number of male in Chennai = 3x
Number of female in Chennai = 2x
Number of male in Bangalore = 7y
Number of female in Bangalore = 3y
Number of population is equal in Chennai and Bangalore
3x + 2x = 7y + 3y
x = 2y
Number of postgraduate male in Chennai = 80/100 * 3x = 2.4x
Number of postgraduate female in Bangalore = 60/100 * 3y = 1.8y
2.4x + 1.8 * (x/2) = 3300
4.8x + 1.8x = 6600
x = 1000
Male population in Chennai and Female population in Bangalore = 3x + 3y = 3x + (3 * x/2)
= 4.5x
Required total = 4.5 * 1000 = 4500
6) Answer: C
Yellow balls from A = 1/2 * 2x = x
Yellow balls from B = 3/5 * 3x = 9x/5
Yellow balls from C = 4/5 * x = 4x/5
Total yellow balls = x + 9x/5 + 4x/5 = 18x/5
Required percentage = (18x/5)/6x * 100 = 60%
7) Answer: E
Number of boys in class A = 4x
Number of girls in class A = 5x
Number of boys in class B = 4y
Number of girls in class B = 3y
5x + 4x – 10 = 4y – 10 + 3y
9x = 7y
x/y = 7/9
8) Answer: A
C’s income = x
Expenditure = y
Savings = s
x = y + s
y + s – s = 12000
y = 12000
Savings = 12000 * ½ = 6000
x = 12000 + 6000 = 18000
B’s income = 2/1 * 18000 = 36000
A’s income = 4/3 * 36000 = 48000
Average income of A, B and C = (48000 + 36000 + 18000)/3 = 34000
9) Answer: C
Let the total amount divided by 70x
Amount received by A and C together = 70x*(5/7) = 50x
And amount received by B = 70x*(2/7) = 20x
Let the amount received by A = 10k and amount received by C will be 150% of 10k = (150/100)*10k = 15k
Amount received by A and C together = 10k + 15k = 25k
Since 50x = 25k
2x = k
Amount received by A = 10k = 10*2x = 20x
Amount received by C =15k = 1500
k =100
2x = 100
x = 100/2 = 50
Therefore, the sum of amount received by A and B = 20x+20x = 40x = 40*50 = Rs. 2000
10) Answer: C
Number of employees in A:B:C= 30: 25: 39
Number of female employees in A = 30x * 5/12 = 12.5x
Number of female employees in B = 3/5 * 25x = 15x
Number of female employees in C = 39x * 6/13 = 18x
Required percentage = (12.5x + 15x + 18x)/94x * 100
= 45.5x/94x * 100
= 48%
