Problem Solving: Percentage Practice MCQ

Question Statement:

10% of inhabitants of a village having died of cholera, a panic set in, during which 25% of the remaining inhabitants let the village. The population is then reduced to 4050. Find the original inhabitants

5500

6000

6500

7000

Explanation:

Correct Answer: B

Let the total number is x, then

(100 - 25)% of (100 - 10)% x = 4050

75% of 90% of x = 4050

$\frac{75}{100}$ × $\frac{90}{100}$ × x = 4050

$\frac{3}{4}$ × $\frac{9}{10}$ × x = 4050

x = $\frac{4050 × 4 × 10}{3 × 9}$

x = $\frac{4050 × 40}{27}$ = 6000
