Question

Jack's mother is 4 times his age . If the sum of their ages is 45 years , what will be their ages 4 years hence ?

Pls I want the answer with full explanation ​

Answer 1

Answer:

let Jack's age be x

mother's age be 4x

sum of ages = x+4x = 5x = 45

so x Jack 's age = 9 .

Mother's age = 4×9=36

After 4 years ,

Jack's age will be 9+4 = 13 years

His mother's age will be 36+4 = 40 years .
