SSC CGL Tier II - 26 October 2023 • Quantitative Aptitude • Q21

If P : Q = 3 : 4 and Q : R = 4 : 7, then find the value of (P + Q) : (Q + R) : (R + P).

Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. 7 : 11 : 10.

P : Q = 3 : 4

Q : R = 4 : 7

Q is equal in both, so we get -

⇒ P : Q : R = 3 : 4 : 7

⇒ (P + Q) : (Q + R) : (R + P) = (3 + 4) : (4 + 7) : (7 + 3) = 7 : 11 : 10
