By selling a watch for 1275, Javed lost 15%. At what price should he sell
to make a profit of 10%?

1650 profit 10%

Step-by-step explanation:

Original Price of Watch = x

15% of x = x*15% = x*0.15

Given

Selling pirce = 1275

Original Price - 15% of original pirce = Selling Price

x-0.15x=1275

0.85x=1275

0.85x/0.85=1275/0.85

x=1500

Original Price of Watch = Rs. 1500

10% of 1500 = 10/100 * 1500 = 1/10 * 1500 = 1500/10 = 150

Selling price at 10% profit = 1500 + 150 = 1650

He sould sell watch to kae for Rs. 1650 to get a profit of 10%

Regular selling price (price before discount) 100%.

Price after trade discount of 15% is 85% of regular selling price..

Price after trade discount reduced to 10% is 90% of regular selling price.

By reducing the trade discount from 15% to 10% meant increasing the selling price by 5% of the selling price before applying the trade discount.
