Answer 1

Hey

Here is your answer,

After 3 years, age of his son = 15
=> present age of his son = 12

at present, the person is 4 times older than his son
=> present age of the person = 4 × present age of his son = 4×12 = 48
=> present age of his wife = 48 - 3 = 45

Age of his wife after 5 years = 45 + 5 = 50

Hope it helps you!

Answer 2

Present  person⇒ 4x  son⇒x  wife⇒ 4x-3
3 years  Son⇒ 15 years
Present age of son⇒ 15-3 = 12
x=12 
wife's present age⇒ 4x-3 = 4(12)-3 = 45
wife's age after 5 years⇒45 +5 = 50
