Question

Find a single equivalent increase if a number is successfully increased by 20 percent,25 percent,and 30 percent

Answer 1

let the initial number be 100
if we increase it by 20% then the new number will be 120
if 120 is increased by 25% then new number will be (125/100)*120 = 150
if 150 is increased by 30 % then new number will be ( 130/100)*150 = 225
one single increase =[(225-100)/100]*100 = 125%
