Question

Mona is 20 percent older then netu than How much netu is older than mona

Answer 1

here's ur answer

let the age of netu be x years.

age of mona=x-20%of x=x-20x/100
age of mona =x-x/5=(5x-x)/5=4x/5

age difference between netu and mona=
x-4x/5=(5x-4x)/5=x/5

netu is older than mona = (age difference/age of mona)×100

netu is older than mona= ( (x/5)/(4x/5) ) × 100
netu is older than mona = (x/5)×(5/4x)×100

=100/4=25 %

:• hence, netu is older than mona by 25%.
