Question

by selling a stool for rs 60.50 carpenter loses 10%. how much percent would he gain or lose by selling it for Rs 82. 50?

Answer 1

SP = 60.50

CP = a

60.50/a  x 100 = 90

90a = 6050

a = 6050/90 = 67.22

CP = Rs. 67.22

He gets profit if he sells for 82.50 by 82.50 - 67.22 = Rs. 15.28

in percent = 15.28 /67.22  x 100 = 22.73%

He would gain 22.73%
