Sumit’s mother is 22 years younger than sumit’s grandmother and 27 years older and Sumit.the sum of their ages is 121 years then the present age of Sumit is _____.
Find age of Sumit (present age)

Answer 1

Answer:

Let the age of Sumit be x years

Sumit's mother's age be ( x+27 ) years

and Sumit's grandmother's age be ( x+27+22 ) years

A/q

x+(x+27)+(x+27+22) = 121 years

x+x+27+x+27+22 = 121

3x+76 = 121

3x = 121-76

3x = 45

x = 45/3

x = 15

therefore, Sumit's age

= x years

= 15 years

Sumit's mother's age

= (x+27) years

= 15+27

= 42 years

Sumit's grandmother's age

= (x+27+22) years

= (15+27+22)

= 64 year's
