Question

A trader buys an article for rs1700,at a discount of 15% in it's printed price.he raises the printed price of the article by 20% and then sells it for rs
2688 including sales tax on the new market price.find the rate of sales tax( 2.) the traders profit as percent

Answer 1

Original price = 100%

1700 is 85% so, now we know 2000 is the printed price.

20% increase = 2400 is new printed price.

Tax = 2688-2400 = 288.

Rate of sales tax = 12%.

 

Traders profit = (2400 -1700) × 100 ÷ 1700 = 700 ÷ 17 or 41.18%

Answer 2

Marked price 
=1700 x 100/85
=2000

new mp=2000 x 120/100
=2400

profit=2688-2400
= 288

rate of tax =
2400 x X/100=288
X =288/24
=12 %

Traders profit = (2400 -1700) × 100 ÷ 1700
 = 7 x 100 ÷ 17
=700/17
=41.17

the profit for trader is 41.17 %
