Answer» Answer: SELLING price(s.p.) = 3,00,000 profit % = 25 % now if for 100 rs he`s GETTING 125 rs.(25% profit) then for 3,00,000 rs what may the cost price? we `ll put in following way 100 - 125 then x- 3,00,000 so 100*3,00,000/125 = 2,40,000 will be the cost price of that car. or let`s put it another way consider cost price(CP)=x sale price(SP)=3,00,000 - - - - - given now profit = SP - CP so profit = 3,00,000 - x profit % = (profit / CP) * 100 25 = (3,00,000 - x / x) * 100 25/100 = 3,00,000 - x / x (1/4) * x = 3,00,000 - x x/4 = 3,00,000 - x x = 4 * (3,00,000 - x) x = 12,00,000 - 4x x+4x = 12,00,000 5x = 12,00,000 x = 12,00,000/5 therefore x = 2,40,000 = CP hence his CP was 2,40,000 |
