SSC GD Constable (English) - 17th November 2021 Shift 2 • Quantitative Aptitude • Q62

Seema is younger than Rima by 8 years. If 4 years back their age were in the ratio 1 : 2, then find the age of seema after 6 years from now.

Show answer & explanation

Correct answer: B

Explanation

The correct answer is Option 2 i.e. 18.

Let the age of Reema and Seema be R and S

Difference between Reema and seema age = R - S = 8      ---- (1)

Four years back, the ratio of their age

⇒ (S - 4)/(R - 4) = 1/2

⇒ 2(S - 4) = (R - 4)

⇒ 2S - 8 = R - 4

⇒ 2S - R = 4       ---- (2)

Solving equation (1) and (2), we get

⇒ S = 12 years

Now,

Seema's age after 6 years = 12 + 6 = 18 years
