If the male population above the proverty line for State B is 2.5 millions, then what is the total population of state B?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e 8 1/3 million
The ratio of male and female in state B above poverty = 2 : 3
The number of males in state B above poverty = 2.5 million
⇒ The number of females in state B above poverty = 2.5 × (3/2)
⇒ 3.75 million
Total population of state B above poverty = 3.75 + 2.5
⇒ 6.25 million
Total population of state B = 6.25 × (100/75)
⇒ 8.33 million or 8 1/3 million
