The ratio of the two natural numbers is 5 : 6. If a certain number is added to both the numbers, the ratio becomes 7 : 8. If the larger number exceeds the smaller number by 10, find the number added? |

Answer» 20 Let the two numbers be 5X and 6X. Let the numbers added to both so that their ratio becomes 7 : 8 be k. (5x + k) / (6x + k) = 7/8 => 40x + 8k = 42x + 7K => k = 2x. 6x - 5x = 10 => X = 10 k = 2x = 20. |
