20% of the inhabitants of a village having died of malaria, a panic set in, during which 30% of the remaining inhabitants left the village. The population was then reduced to 12,000. What was the number of inhabitants initially (Consider integral part only)
Answer & explanation
Correct answer: option 2
According to question ,
Let population of village = 100
20% of the inhabitants died of malaria
Remaining = 80
30% of the remaining inhabitants left the village
Remaining = 70% of 80 = 56
Given :
56 = 12000
100 = \(\frac{12000}{56}\) × 100 = 21428.5714
Ans = 21428
