  1. Step-by-step explanation:

    We are given that the price of gold is directly proportional to square of its weight.

    => Price = k*weight^2

    Let us say initially the weight of the nugget was 6 units

    => P(original) = k*6^2 = 36k

    After breaking it down into three pieces, we get the weights as 3, 2, and 1

    => P(3) = k*3^2 = 9k

    => P(2) = k*2^2 = 4k

    => P(1) = k*1^2 = k

    => P(new) = 9k + 4k + k = 14k

    Loss = 36k – 14k = 4620 Rs.

    => 22k = 4620 Rs.

    => k = 210

    => Price (original) = 210*36 = 7560 Rs.
