Question

After getting 2 successive discounts, a shirt with a list price of Rs 150 is available at Rs 105. If the second discount is 12.55,find the first discount.

Answer 1

Let the first discount be x% 

Then,87.5% of (100-x)% of 150= 105 

87.5/100*(100-x)/100*450=150=>105=>100-x=(105*100*100)/(150*87.5)=80 

x=(100-80)=20 

first discount = 20%
