Answer 2

Answer:

33 years and 4 months old

Step-by-step explanation:

As we know that the man is 20% older than his sister and age of man is 40

let us consider that the age of his sister is 100

that's why man's age is 120 bcoz man is 20% more

now 100 = ?

IF 120 = 40

I.e 100/120 × 40

100/3

= > 33 years and 4 months
