An electrician bought an old fan for Rs. 420 and spent 25% of it on repairing. If he wants to make a profit of Rs. 126, what percentage of the cost price should be added to it ?

Answer»

55 %



Reparing cost = 420 x 25/100 = 525
Selling price = 525 + 126 = 651
∴ % RISE = 651 - 420/420 x 100 = 55%
