A merchant who marked his product up by 50% subsequently offered a discount of 20%. What is the percentage profit that the merchant make after offering the discount?
(1) 30%
(2) 125%
(3) 25%
(4) 20%
The easiest way to solve these kinds of problems is to assume a cost price
Let us assume that the cost price = Rs.100
The merchant marks his goods up by 50%.
= 100 + 50% of 100 = 100 + 50 = 150
Now, the merchant offers a discount of 20% on his quoted price
Therefore, amount of discount = 20% of 150 = 20% of 150 = 30
Therefore, he finally sells it for 150 – 30 = 120.
Net profit = 20 ( for 100 Rs)
Hence, his % profit = = 20%.
The sum of the even numbers between 1 and n is 79*80, where n is an odd number, then n=?
I will post the answer in my next post:-)
