Answers :
Directions (1-5) :
1) Answer: C
The total number of English monthly magazine readers in January and April together
= > 15000 + 19000 = 34000
The total number of Hindi monthly magazine readers in February and June together
= > 14000 + 22000 = 36000
Required difference = 36000 – 34000 = 2000
2) Answer: A
The total number of English monthly magazine readers in February and May together
= > 12000 + 18000 = 30000
The total number of Hindi monthly magazine readers in January and March together
= > 18000 + 17000 = 35000
Required ratio = 30000: 35000 = 6: 7
3) Answer: D
The total male English magazine readers in March
= > 16000 * (5 / 8) = 10000
The total female Hindi magazine readers in April
= > 15000 * (8/ 15) = 8000
Required difference = 10000 – 8000 = 2000
4) Answer: B
The average number of Hindi magazine readers in all the given months together
= > (18000 + 14000 + 17000 + 15000 + 19000 + 22000) / 6
= > 105000 / 6
= > 17500
5) Answer: C
Total number of English magazine readers in March and June together
= > 16000 + 20000 = 36000
Total number of Hindi magazine readers in April and May together

Required % = (36000 / 34000) * 100 = 105.88 % = 106 %
Directions (6-10) :
6) Answer: A
Let the train length be x,
12 = (x + x) / [(40 + 50) * (5/18)]
12 = (2x * 18) / (90 * 5)
(12 * 90 * 5) / 36 = x
x = 150 m
7) Answer: A
The difference between the compound interest and the simple interest for 2 years is,
Diff = Sum * (r / 100)2
= > 48000 * (8 / 100)2
= > Rs. 307.20
8) Answer: D
The area of the square = 2401 sq cm
a2 = 2401
Side of the square = 49 cm
The radius of the cylinder = (4 / 7) * Side of the square
= > (4 / 7) * 49
= > 28 cm
The height of the cylinder = 36 cm
The volume of the cylinder = πr2h
= > (22 / 7) * 28 * 28 * 36
= > 88704 cm3
9) Answer: B
The share of P, Q and R,
= > [3x * 6 + (3x + 5000) * 6]: [4x * 6 + (4x – 10000) * 6]: [6x * 12] = 7: 6: 12
= > [18x + 18x + 30000]: [24x + 24x – 60000]: [72x] = 7: 6: 12
= > [36x + 30000]: [48x – 60000]: [72x] = 7: 6: 12
According to the question,
= > [36x + 30000] / 72x = (7 / 12)
= > 36x + 30000 = 42x
= > 6x = 30000
= > x = 5000
The initial investment of R = Rs. 30000
10) Answer: C
The sum of the present age of A and B together = The sum of the present age of B and C together
A + B = B + C
A = C
Let the present age of A and C be x,
x + x + (x – 8) + 28 = 20 * 4
3x + 20 = 80
3x = 60
x = 20
The present age of C = 20 years
