According to the question, Present ages of (X + Y) = 45 × 2 = 90…. (1) Than, the Present ages of (X + Z) = 32 × 2 = 64…. (2) Than, the Present ages of (Y + Z) = 12 × 2 = 18….. (3) Therefore From equations (1), (2) and (3), we get Present ages of (X + Y + Z) = (90 + 64 + 18)/2 = 86 years Therefore From equation (3)we will get the, present age of ‘X’ = 86 – 18 = 68 years
