(#M40001746) TCS QUESTION 2010 question Keep an EYE

If on an item a company gives 25% discount, they earn 25% profit. If they now give 10% discount then what is the profit percentage.
(a) 40% (b) 55% (c) 35% (d) 30%

Solution

let the selling price is 100 rupee
on giving 25 % discount the price will be 75,on selling the object in 75 rupee profit = 25 % so original cost will be 75*100/125 = 60
now on giving 10 % discount selling cost will be 90 it means 30 rupee gain on an investment of 60 rupee so profit on investment = 30*100/60 = 50 % (correct answer)
none of the option is correct
if we calculate profit % on the basis of print price then it will be 30*100/100 = 30 but this is not a true method
