Question

Jasleen marks her goods at 30% above the cost price and allows a discount of 25% on the marked price . find her gain or loss per cent .

Answer 1

LET COST PRICE BE Y
THEN, MARKED PRICE IS =30/100 *Y+Y =1.3Y

AND SELLING PRICE= MARKED PRICE-DISCOUNT

 i.e,1.3Y - 25%of 1.3Y=> 1.3Y - O.325Y=1.075Y
NOW SELLING PRICE - COST PRICE =PROFIT=(1.075Y - Y)%=0.75% OF COST PRICE

now
