Prakruthi’s age is 6 time Sahil’s age. After 15 years prakruthi will be 3 times as old as Sahil. Find their age. |

Answer» Let Sahil’s present age be x. Prakruthi’s present age is 6x, 15 years later Sahil age will be (x + 15) years and Prakruthi age will be (6x + 15) years. Given that Prakruthi age will be 3 times as old as Sahil. ∴6x+15 = 3(x+15) 4 6x+ 15 = 3x + 45 6x – 3x = 45 – 15 3x = 30 x = \(\frac{30}{3}\)= 10 Sahils age = x = 10 years Prakruthis age = 6x = 6 x 10 = 60 years |
