Question 37
There is an article of Rs. 100. Its price is raised initially by 10% and then again by 10%. How many rupees have been increased ?
Solution
Cost of the article is 100 Rs. Initial increase = 10%
So, cost = 100 * 110/100 = 110 Rs
Second increase = 10 %
So, cost = 110 * 110/100 = 121
Total increase = 121 - 100 = 21 rupees
