Answer» LET the current age of Rahul and Haroon be 5X and 7X respectively Four years later their ages become 5x + 4 and 7x + 4 respectively. According to the question, 5x + 4 +7x + 4 = 56 or 12x + 8 = 56 Transposing 8 to the RHS we get, 12x = 48 Dividing both sides by 12 gives, x = 48/12 = 4 Thus current age of Rahul = 5*4 = 20 Haroon = 7*4 = 28 |
