Question 107

The marked price of a watch was 720. A man bought the same fort 550.80 after getting two successive discounts, the 1st being 10%. What was the 2nd discount ?

Solution

it is given that marked price of a watch = Rs 720

Now first discount is = 10%

Price after 1st discount = 0.9 × 720 = Rs 648

Now let the 2nd discount be y%

So price after 2nd discount is mentioned as = Rs 550.80

648 - $$\frac{y}{100}$$ × 648 = 550.80

1- $$\frac{y}{100}$$ = 550.80/648

y = 0.15 × 100 =15 %

So 2nd discount = 15%
