If the price of petrol is increased by 20%, by what percentage should the consumption be decreased by the consumer, if the expenditure on petrol remains unchanged?

A) \( \Large 16\frac{2}{3} \)
B) \( \Large 6\frac{2}{3} \)
C) 8%
D) 15%

Correct Answer:

A) \( \Large 16\frac{2}{3} \)

Description for Correct answer:
Here, a = 20%

Required percentage loss = & 100+ a X1009

= \( \Large \frac{a}{100+a} \times 100\% \)

= \( \Large \frac{20}{100+20} \times 100\% \)

= \( \Large \frac{20}{120} \times 100\% = 16\frac{2}{3}\% \)
