Data Interpretation Quiz – 08 May

Q1. Correct Option: C
Let the number of adult population of Pakistan = x
Then, 60% of x = 960
Therefore,
(100 – 60)% of x = 40% of x = (960×40)/60 = 640 million
The number of adult females =  (17×640)/20 = 17 × 32 = 544 million

Q2. Correct Option: B
The total number of adult females who are financially unstable
= (1×560)/2 = 280 million
Let the number of adult population of India = x
Then, 40% of x = 560
Therefore,
(100 – 40)% of x = 60% of x = (560×60)/40 = 840 million
The number of adult females = (5×840)/12 = 350 million
The population of adult females in India = 280 + 350 = 630 million

Q3. Correct Option: A
Let the number of adult population of Pakistan = x
Then, 60% of x = 960
Therefore, adults who are financially stable
(100 – 60)% of x = 40% of x = (960×40)/60 = 640 million
The number of adult males who are financially stable = (3×640)/20 = 3 × 32 = 96 million
let the number of adult population of Pakistan = x
Then, 60% of x = 960
X = (960x10C)/60 = 1600
The reqd. % = (96 x 100)/1600 = 6%

Q4. Correct Option: D
Let the number of adult population of Pakistan = x
Then, 60% of x = 960
X = (960×100)/60 = 160
let the number of adult population of Afghanistan = y
Then, 96% of y = 300
Y = (300 x 100)/96 = 312.5
The required sum = 1600 + 312.5 = 1912.5 

Q5. Correct Option: C
Let the number of adult population of Bangladesh = x
Then, 72% of x = 900
X = (900 x 100)/72 = 1250
(100 – 72) = 28% of 1250 = 350 million
The number of adult males in Bangladesh who are financially stable
= (4 x 350)/7 = 200 million
Let the number of adult population of Indonesia = y
Then, 50% of x = 644
X = (644 x 100)/50 = 644 x2 
(100 – 50) = 50% of 644 × 2 = 644 million
The number of adult females in Indonesia who are financially stable
= (2 x 644)/5 = 257.6 million
The required difference = 257.6 – 200 = 57.6 million
