Question

raghav is 4 times as old as his son vikram .after five years raghav will be 3 times as old as his son then find thier present ages

Answer 1

Raghav's age = x
His father's age = 4x
After 5 years,
Raghav's age = x +5
His father's age =4x+5
A/q
4x+5=3(x+5)
4x+5=3x+15
4x-3x=15-5
x=10
So,Raghav's current age =10
And his father's current age=40
*Hope this will help you*

Answer 2

${\bold{\underline{\boxed{Answer=10\:years}}}}$

Explanation : Let Vikram's age = x

$\implies$ Raghav age = 4x

After five years :

$\implies$ Vikram = x+5 years; Raghav = 4x+5 years

Now, according to the question = 3(x+5)=4x+5

$\implies$ 3x + 15 = 4x + 5

$\implies$ 15 - 5 = 4x - 3x

$\implies$ x = 10

Therefore, Present age of son is x=10 years and present age of father is 4x = 40 years.
