Answer 1

Answer:

Let Nath's present age be = 3x

Let Mother's present age be = 7x

Age of Nath at birth = 0 years

Age of Mother at his birth = 20 years

Mother's present age = 20 + Nath's present age

=> 7x=20 + 3x

=>7x - 3x=30

=> 4x=20

=> x=20/4

=> x=5

Therefore Nath's present age = 3x = 3 × 5 = 15 years

Therefore Mother's present age = 7x = 7 × 5 = 35 years

Nath age is 15

Mother age is 35

Step-by-step explanation:

keep going until
