  1. Given : A goldsmith sells gold at Rs 3,500 per gm and diamond at Rs 1,000 per gm. He sold a particular diamond ring made of gold weighing 5 gm for Rs. 13, 500.

    Solution :

    Let weight of diamond in the ring is x gm .

    so,

    → weight of gold = (5 – x) gm .

    then,

    → Total cost = Rs.13500

    → 3500 * (5 – x) + 1000 * x = 13500

    → 17500 – 3500x + 1000x = 13500

    → 2500x = 17500 – 13500

    → 2500x = 4000

    → x = (4000/2500)

    → x = (8/5)

    therefore,

    → 5x = 5 * (8/5) = 8 gm (Ans.)
