Question
The ratio of two numbers ‘M’ and ‘N’ is 2:3,
respectively. If 12 is added to each of ‘M’ and ‘N’, then the ratio of ‘M’ and ‘N’ becomes 3:4. The sum of ‘M’ and ‘N’ is:Solution
Let the two numbers ‘M’ and ‘N’ be ‘2x’ and ‘3x’, respectively ATQ; (2x + 12)/(3x + 12) = 3/4 Or, 8x + 48 = 9x + 36 Or, x = 12 Now, sum of ‘M’ and ‘N’ = 2 × 12 + 3 × 12 = 60
