Question

Manoj 's income incresed by 20% and the decresed by 20%. what is the total percentage change in Manoj ,s income ?

Answer 1

4 percentage changes only

1. Take manoj income is X=100 (Assumption)
2. 20% increases basic income so, (20/100)*100=20
so, increased with total is →1+2→(100+20)
=120 (Assume it Y)

Now, Income Y is decreased 20%
so, (20/100)*120
=24 (assume it Z)
Decreases is Z-Y=120-24
=96 (assume it A)
So,the different between A and X is 4
So we say answer is 4%

Answer 2

answer = 4 percent decrease
