**Quantitative Aptitude – Arithmetic – Percentages**

**Question**

In a village, the production of food grains increased by 40% and the per capita production of food grains increased by 27% during a certain period. The percentage by which the population of the village increased during the same period is nearest to

A) 16

B) 13

C) 10

D) 7

**Answer**

Option (C)

**Solution**

From CAT 2017 – Quantitative Aptitude – Arithmetic – Percentages, we can see that,

The total production of food grains (Initial) = t

The total production of food grains (Final) = t’ = 1.4t

Population (Initial) = n

Population (Final) = n’

Per capita food production (Initial) = t/n

Per capita food production (Final) = t’/n’ = 1.4t/n’

1.4t/n’ = t/n

=> n’ = 140n/127

Population increased by [(140n/127 – n)/n] * 100 = 10% (Approximately)

Option C is the right answer.
