Please tell the answer step-by-step..Please..​

Answer 1

Step-by-step explanation:

let age of raj = 100years

present / original age of puneet = (100-20)yr

= 80 yrs

if puneet is 80yrs old , then raj elder than puneet by = 20yrs

if puneet is 1 yrs old , then raj elder than puneet by = 20/80 yrs

if puneet is 100 yrs old , then raj elder than puneet by = (20/80) 100 %

= (1/4) 100 %

= 25%
