Question

Mona is 20% younger than Neetu. How much percent is Neetu older than Mona?

Answer 1

Let Neetu's age = 100 years
then Mona's age

= 100 - 20

= 80 years

Difference of ages

= 100 - 80

= 20 years

If Mona is 80 years, then Neetu is older than Mona by = 20 years
If Mona is 1, year, then Neetu is older than Mona by = `(20)/(80)`years
If Mona is 100 years, then Neetu is older than Mona by

= `(20)/(80) xx 100`years

= `(20 xx 100)/(80)`

= 25%
