According to the question, Present ages of (X + Y) = 16 × 2 = 32…. (1) Than, the Present ages of (X + Z) = 56 × 2 = 112…. (2) Than, the Present ages of (Y + Z) = 22 × 2 = 44….. (3) Therefore From equations (1), (2) and (3), we get Present ages of (X + Y + Z) = (32 + 112+ 44)/2 = 94 years Therefore From equation (3)we will get the, present age of ‘X’ = 94 – 44 = 50 years
