Question
Rs 625 is to be divided among A, B and C so that A gets
2/9 of B’s share and C gets 3/4 of A’s share. Share of C is:Solution
Let the B’s share be Rs x A’s share = 2x/9 C’s share = 3/4×2/9 x = 1/6 x ⇒x + 2x/9 + 1/6 x = Rs 625 ⇒ (18x +4x+3x )/18 = 625 x = (625 ×18)/25 = 450 ∴ A’s share = Rs 100 ∴ B’s share = Rs 450 ∴ C’s share = Rs 75
