Answer:
original price of the diamond = 1,00,000
Step-by-step explanation:
diamond broke into four pieces with weights in the ratio 1:2:3:4
so original weight of unbroken diamond is 1x + 2x + 3x + 4x = 10x
so original price of unbroken diamond is (10x)^2 * y = 100x^2 * y........(1)
y is certain rate of diamond
total price all broken diamond = [(1x)^2 + (2x)^2 + (3x)^2 + (4x)^2] * y = 30x^2 * y
lost money = 100x^2 * y - 30x^2 * y = 70x^2 * y
70,000 = 70x^2 * y
1000 = x^2 * y sub in (1)
100(x^2 * y )= 100 * 1000 = 100,000
