A trader gains 15% after selling an item at 10% discount on the printed price. The ratio of the cost price and printed price of the item is

Answer»

GIVEN,

G% = 15%

D% = 10% ON MP


LET MP = Rs. 100

SP = MP - MP *(D%/100)

SP = 100 - 100* (10/100)

SP = Rs. 90


So,


CP = (SP*100)/(100+G%)

CP = (90*100)/(100+15)

CP = (9000)/115

CP = 1800/23


CP : MP = (1800/23):100

CP/MP = 1800/2300

CP/MP = 18/23

CP : MP = 18 : 23



Please let me know if the answer is correct.
