leela sold a gold necklace at a profit of 7%. If she had sold it for Rs294 she would have get 1o% profit. Find the cost price

Answer»

By INCREASING SP by ₹294 increases the PROFIT from 7% to 10%

So INCREASE in profit% = 10% - 7% = 3%

profit % = profit/CP × 100
3 = 294/CP × 100
CP = 294/3 × 100
CP = ₹9800
