Question

Help me solve this problem!

Answer 1

i)
CP of the 100g of gold = Rs 54000
gain percent = 10
gain = 10% of CP
= (10/100)×54000
= 10×540
= Rs 5400
now
SP of 100g of gold = CP + gain
= 54000 + 5400
=Rs 59400
now SP of 10g of gold = 59400/10
=Rs 5940
therefore the SP of 10g of gold = Rs 5940

ii)
Profit percent of the wholesaler = 8
Profit of the wholesaler = 8% of CP of the 100g of gold
= (8/100)×54000
= 8×540
= Rs 4320
SP of the wholesaler = CP of the goldsmith
=> SP of the wholesaler = Rs 54000
now CP of the wholesaler = SP - Profit
= 54000 - 4320
= Rs 49680
now CP of 10g of gold bought by the wholesaler = 49680/10
= Rs 4968
therefore CP of 10g of gold for the wholesaler is Rs 4968
