Let Vinay’s present age be x

Then, his mother’s present age = 3x

After 5 years,

Vinay’s age = x + 5

Vinay's mother’s age = 3x + 5

Sum of Vinay and Vinay's Mother's age after 5 years = 70

⇒x + 5 + 3x + 5 = 70

⇒ 4x+10 = 70

⇒4 x = 60

⇒ x = 15

⇒ 3x45

∴Vinay’s age is 15 years and his 

mother’s age is 45 years
