___________________________

★ Given★

1 . The age of Ramu's father is 4 times that of Ramu

2 . After 5 years it would be 3 times

★ To Find ★

Their present ages

★ Solution ★

Let the present age of Ramu be , " x "

So , Present age of Ramu's Father = " 4x "

[ ∵ From 1st condition ]

After 5 years ,

→ Ramu's age = x + 5

→ Ramu's father age = 4x + 5

So ,

A/c to 2nd condition ,

⇒ 4x + 5 = 3 ( x + 5 )

⇒ 4x + 5 = 3x + 15

⇒ 4x - 3x = 15 - 5

⇒ x = 10

So , Present age of Ramu ,

x = 10 years ★

Present age of of Ramu's father ,

★4x = 40 years ★
