Two years ago, the ratio of ages of Naresh and Suresh was 3:2. If one year hence, the ratio of their ages will be 7:5, what is the sum of their present ages?

30 Yr 32 Yr 34 Yr 36 Yr |
34 Yr |
Let two years ago, the ages of Naresh and Suresh was 3X and 2X. \(\frac{\text{3 x + 3}}{\text{2 x + 3}}\) = \(\frac{7 }{5 }\) 15X + 15= 14X + 21 X = 6 Present age of Naresh = 3 x 6 + 2 = 20 years Present age of Suresh = 2 x 6 + 2 = 14 years ∴Sum of their present ages = 20 + 14 = 34 years |
