Question

Manoj's income increased by 20% and then decreased by 20% what is the total percentage change in Manoj's income?​

Answer 1

Answer:

4% decrease

Step-by-step explanation:

Let Manoj's income be Rs.100.

Income after increasing = 120% of Rs.100 = 120/100 x Rs.100 = Rs.120

Income after decreasing = 80% of Rs.120 = 80/100 x Rs.120 = Rs.96

Net decrease = Rs.(100-96) = Rs.4

Hence, percentage change = 4% decrease
