(1) After 5 years from today,Daughter’s age = 7x years Son’s age = 6x years ∴Daughter’s present age = (7x – 5) years Son’s present age = (6x – 5) years ∴ Poorvi’s present age = (7x – 5 + 6x – 5 + 8) years = (13x – 2) years ∴ Poorvi’s husband’s present age = (13x + 5) years According to the question, ⇒13x+5=3(6x–5) ⇒ 13x+5=18x–15 ⇒18x–13x=20⇒5x=20 ⇒x = 4 ∴ Daughter’s present age= 7x – 5=7×4–5=23years
