Question

By selling a shirt for rs 135 a shopkeeper loses 10%how much percentage would he gain or lose for rs177.solve it

Answer 1

Answer:

He will gain 18 per cent.

Step-by-step explanation:

Profit (%) = Profit/CP * 100

               = (SP - CP)/CP * 100

                = (SP/CP - 1) * 100

As he has made a loss, his Profit (%) = -10. Also SP = 135

Susbtituting in the above equation, we get:

-10 = (135/CP - 1) * 100

-10/100 = (135/CP - 1)

135/CP -1 = -0.1

135/CP = 0.9

CP = 135/0.9 = 150

Cost Price of the shirt is Rs.150

Now, if he sells the shirt for Rs.177, we have SP = 177. CP = 150

Profit = SP - CP = 177-150 = 27

Profit (%) = Profit/CP * 100

               = (27/150) * 100

                = 18%
