When the price of a cycle is decreased by 20%,then the selling is increased by 20%. What is the impacton the receipt of the revenue?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 4% loss

Let CP of a cycle be 100Rs and person sells 100 units of cycles 

then, revenue collected by person = 100 × 100 = 10000 Rs

When the price of a cycle is decreased by 20%,and the selling is increased by 20% then 

New CP = 100 - 20% of 100 = 80 Rs

New selling = 100 + 20% of 100 = 120 units

New revenue = 80 × 120 = 9600

 = (10000 - 9600) × 100/10000

400 × 100/10000 = 4% loss
