Question

One question for my exam.The age of Rajeev and Sanjeev are in ratio of 5:7.Ten year later,the ratio of their ages will be 7:9.Find their present ages.

Answer 1

Answer:

Rajeev = 25

Sanjeev = 35

Step-by-step explanation:

Present age

Rajeev = 5x

Sanjeev = 7x

10 Years later

Rajeev = 5x + 10

Sanjeev = 7x + 10

According to questions 10 years later their age was in the ratio of 7:9

So , (5x + 10)/(7x+10) = 7/9

= 45x + 90 = 49x + 70

= 20 = 4x

x = 20/4 = 5

Age of Ranjeev = 5x = 25

Age of Sanjeev = 7x = 35
