IB exams

If selling price of an article is Rs. 250, profit percentage is 25%. Find the ratio of the cost price and the selling price?

Answer 1

SP = (100+%profit)/100 * CP = 125/100 * CP    => ratio = 4/5

=======================
selling price = SP = Rs 250.
cost price = CP

Profit = 25% CP = 0.25 CP

SP = CP + profit = CP + 0.25 CP = 1.25 CP

CP / SP = CP / (1.25 CP) = 4/5 = 0.80  or 4 : 5
