Question

the ratio of age of ravi and kavi is 3:4 sum of their ages after 5 years will be 45 find their present age?
​

Answer 1

Let the present age of Ravi = 3x
and the present age of Kavi = 4x

After 5 years,
Ravi age = 3x + 5
Kavi age = 4x + 5

According to statement
3x + 5 + 4x + 5 = 45
7x + 10 = 45
7x = 35
x = 5

So age of Ravi = 3 x 5 = 15 years
Age of Kavi = 4 x 5 = 20 years
