Question

the ages of rama and bheema are in ratio 4:9. Ten years later the sum of their ages will be 189 years. What are their present ages​

Answer 1

Let their present ages be x

ratio = 4:9

= 4x :9x

Ten years later

sum of their ages =189

Rama's age = 4x+10

Bheema's age =9x+10

Therefore the equation is

4x+10+9x+10=189

4x +9x +20=189

Transpose 20 to RHS

13x=189-20

13x=169

13x/13=169/3

x=169/3
