Answer» Correct Answer - Option 1 : Rs. 5500 GIVEN : The ratio of weight of pieces is 3 : 2 : 1 The diamond of worth Rs. 9000 is accidently dropped and broke into 3 pieces. CONCEPT : The cost of a piece of diamond varies with the square of its weight. ⇒ Price = k × weight2......(k is any constant) ASSUMPTION : Let the weight of a piece of diamond be (3a + 2a + a = 6a) CALCULATION : The initial value of diamond = 36ka2 ⇒ 36ka2 = 9000 Then, The new value of diamond becomes = k (9a2 + 4a2 + a2) = 14ka2 New value of diamond = (14 × 9000)/36 = Rs. 3500 ∴ Loss occurred = 9000 - 3500 = Rs. 5500 |
