Answers :
Directions (1-6):
1) Answer: C
Required total = 4000 + 4000 = 8000
2) Answer: C
Required Average = (9000 + 9000 + 5000 + 12000 + 6000)/5 = 8200
3) Answer: B
B and E female population = 6000 + 4000 = 10000
A and C female population = 3000 + 3000 = 6000
Difference = 10000 – 6000 = 4000
4) Answer: C
Number of above poverty population in B = 17/30 * 15000 = 8500
Number of male population in A = 9000
Difference = 9000 – 8500 = 500
5) Answer: A
Number of female population in D in 2019 = 4000 * 140/100 = 5600
Number of male population in D in 2019 = 12000 * 80/100 = 9600
Total population in D in 2019 = 5600 + 9600 = 15200
6) Answer: D
Required ratio = (5000 + 6000):(3000 + 6000 + 4000 + 4000)/4
= 11000:4250
= 220:85
= 44:17
Directions (7-9):
Box A:
Total = 36
Red = 36 * 3/9 = 12
Blue = 36 * 2/9 = 8
Green = 36 * 4/9 = 16
Box B:
Total = 125/100 * 36 = 45
Red = 125/100 * 12 = 15
Blue = (45 – 15) * 3/5 = 18
Green = 30 * 2/5 = 12
Box C:
Total = 45 + 5 = 50
Red = 15 – 1 = 14
Blue = 12 + 8 = 20
Green = 50 – 14 – 20 = 16
7) Answer: B
Total = 16 + 12 + 16 = 44
8) Answer: E
Required ratio = (12 + 15 + 14):45
= 41: 45
9) Answer: E
Required percentage = [(8 + 18 + 20)/50] * 100
= 92%
10) Answer: E
From statement I,
(l – 3) * (b + 5) = 117
So, Statement I alone is not sufficient to answer the question.
From statement II,
l – 3 + 4 = b + 5
l = 4 + b
So, Statement II alone is not sufficient to answer the question.
From I and II
(l – 3) * (b + 5) = 117
(4 + b – 3) * (b + 5) = 117
(b + 1) * (b + 5) = 117
b2 + 6b – 112 = 0
Solving this,
b = -14, 8
b = 8 (neglecting –ive value)
l = 8 + 4 = 12
Area = lb = 12 * 8 = 96
Both statements are necessary to answer the question.
