Question

Ranjay's salary was raised by 20% and then reduced by 20%. Find the percentage change
in his salary​

Answer 1

Answer:

4% decrease

Step-by-step explanation:

Let his original salary be Rs.100.

Salary after increasing 20% = 120% of Rs.100 = Rs.120

Salary after decreasing 20% = 80% of Rs.120 = Rs.96

96 < 100

Hence, net decrease = 100 - 96 = 4

Percentage change = 4/100 × 100 = 4%
