In a village, 30% of the villagers belong to upper economic class. The number of villagers who belong to middle economic class are 3/2 of the number of villagers who belong to lower economic class. If 6860 villagers belong to lower economic class, what is the population of the village ?

A) 22600
B) 24500
C) 26000
D) 25500
E) 24300

Correct Answer:


B) 24500

Description for Correct answer:
Villagers belong to lower economic class = 6860

Villagers belong to middle economic class = \( \frac{30}{2} \times 6860 = 10290 \)

Let the population of the village be x

According to question,

\( \frac{30}{10}x+10290+6860 = x \)

\( 17150 = x-\frac{3}{10}x \)

\( \frac{17150 \times 10}{7}=x \)

x = 24500
