Answer 2

AnswEr :

Let the Present Age of Saran be n yrs and Present Age of his son Sankar be m yrs.

⋆ Saran is 6 times as old as his son Sankar.

⇝ Saran = 6 times of Sankar

⇝ n = 6 × m

⇝ n = 6m — eq. ( I )

⋆ After 4 years, Saran will be 4 times as old as his Son Sankar.

⇝ Saran = 4 times of Sankar

• After 4 yrs means increase of 4 in Age

⇝ (n + 4) = 4 × (m + 4)

⇝ n + 4 = 4m + 16

⇝ 6m + 4 = 4m + 16 — [ from ( I )]

⇝ 6m - 4m = 16 - 4

⇝ 2m = 12

• Dividing Both term by 2

⇝ m = 6 Yrs. [ Sankar Present Age ]

• Putting the Value of m in ( I ) :

⇝ n = 6m

⇝ n = 6 × 6

⇝ n = 36 Yrs. [ Saran Present Age ]

∴ Present Age of Saran will be 36 Yrs and Present Age of Sankar will be 6 Yrs.
