Answer:
Step-by-step explanation:
Let his income be x
Increase in income = 20x/ 100
Increased income = x+ 20x/100
=120x/100
Decrease in income = 20/100 × 120x/100
=6x/25x
Decreased income = 120x /100 -6x/25x
(120x - 24x)/ 100
=96x/100
Change in income = x-96x/100
=4x/100
Change % = (4x/100 × 1/x × 100)%
=4% decrease
