dinesh is younger to Reagan by 9 years. if their ages are in the respective ratio of 4:5,how old is finish?
​

Answer 1

Answer:

Reagan = 45 years old

Dinesh= 36 years old

Step-by-step explanation:

Let Reagan's age be x,

Therefore, Dinesh's age is x-9

4/5 = x-9/x

4x = 5x -45

-x = -45

Therefore x=45(Reagan)

and dinesh is 45-9= 36

Answer 2

Let Roshan's age be x years.

Then,Dinesh's age = (x - 9) years.

(x - 9)/x = 4/5

        x = 45

Hence, Dinesh's age = (x - 9) = 36 years.
