Question

A man’s salary increases 25%to20000.find its original salary?

Answer 1

X x 100 + 25 / 100 = 20000
X × 125/100 = 20000
X × 5/4 = 20000
X= 20000×4/5
X = 4000×4
16000

Answer 2

Let the person's initial salary be x

x + 25% of x = 20000

x + 25x/100 = 20000

x + x/4 = 20000

5x/4 = 20000

x = 20000*4/5

x= 16000

The initial salary was Rs.16000
