Rs 720 is to be divided among P, Q and R so that P gets 3/5 of Q’s share and R gets 1/3 of P’s share. Share of R is:
Let the Q’s share be Rs x P’s share = 3x/5 R’s share = (1/3) × (3/5) x = (1/5) x ⇒ x + (3x/5) + (1/5) x = 720 ⇒ (5x + 3x + x)/5 = 720 x = (720 × 5)/9 = 400 ∴ P’s share = Rs. 240 ∴ Q’s share = Rs. 400 ∴ R’s share = Rs. 80
