Question

Mona is 29% younget than Neetu .By 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 years

If Mona is 100 years, then Neetu is older than Mona by = 20/80 x 100 years= (20 ×100)/80

= 25%

Answer 2

Answer:

$\huge \tt \underline\red{↪ Solution}$

Neetu Age = 100 years

then Mona age= 100-20 = 80 years

differences of age

→ 100-80

= 20years

if Mona 80 years, then Neetu is older then Mona by = 20 years

if Mona is 1 year then Neetu is older

$\tt \: tan \: mona \: by = \frac{20}{80} years$

if Mona is 100 years then Neetu is older than Mona By

$\tt \: = \frac{20}{80} \times 100 \: years\\ \tt \:$

$\tt \: = \frac{20 \times 100}{80}$

$= \tt \: 25\%$
