Question

31. The ages of ramesh and suresh are in the ratio 7:5. Ten years later, the ratio of their ages will be 9:7. Find their present ages. O none of these Ramesh's age = 30. Suresh's age = 25 Ramesh's age = 35. Suresh's age = 25 Ramesh's age = 25. Suresh's age = 35 Required​

Answer 1

Answer:

35 and 25

Step-by-step explanation:

Let ramesh be A

Let suresh be B

Let the present age of A= 7x years

The present age of B= 5x years

After 10 years, their ages will be  

A=7x+10 years and

B=5x+10 years

The ratio of their ages after 10 years is 9:7.

∴  

5x+10

7x+10

​

=  

7

9

​

 

⇒49x+70=45x+90

⇒49x−45x=90−70

⇒4x=20

⇒x=5

∴ Present age of A= 7×5=35 years and present  

age of B= 5×5=25 years
