Question

if the difference of ages between arun and deepak is 14years and seven years ago ,their ration was 5:7 then find the present age of deepak

Answer 1

Seven years ago, let Arun's and Deepak's age be 5x and 7x years respectively. 

Arun's present age = (5x+ 7) years 

Deepak' present age = (7x + 7) years 

According to the question, 

7x + 7 - 5x - 7 = 14 

=> 2x = 14 

=> x = 14/2 = 7 

Therefore, Deepak's present age=7x + 7 = 7×7+7 = 56 years
