Trisha's present age = x years (Let) ∴ Samartha's present age = 5x years Phalgunl's present age = (x + 26) years According to the question. 3 (5x- 10) - 2 (x + 26 10) = 42 ⇒ 15x- 30-2x 32 = 42 ⇒ 13x = 42 +62 = 104 ⇒ x =
104
13
= 8 ∴ After 12 years. Phalguni's age = (x + 26 + 12) years = (8 + 38) = 46 years Samartha's age = (5x + 12) years = (5 x 8 + 12) years = 52 years Required ratio = 46.52 = 23 : 26
