Question

the Marked price of an article is 33500 and the rate of GST is 12% A shopkeeper allows a discount or 20% and still makes a profit of 10% find the original cost price of the article and the selling price including GST​

Answer 1

A merchant allows a 20% discount

price after reduction 33,500*0.8=$26800

decrease 20% =1-(120/100)=08

the merchant always makes a 10% profit on this item

10% (increase) coefficient of 1.10

initial cost price: 26800/1.1=$24363.63636

tps = increase of 12% = coefficient 1+(12/100)= 1.12

sales price GST included: $24,363.63636*1.12=27287.27272=$27287.28
