A shopkeeper gives two successive discounts on a watch marked ₹2,750. The first discount given is 10 %. If the customer pays ₹ 2,103.75 for the watch, then what is the second discount?

15%

After 1st discount amount = 2750 × 90%

⇒ 2475

Let the second discount be a%

According to the question,

2475 × (100 - a)% = 2103.75

⇒ \(\frac{100  - a}{100}\)= \(\frac{2103.75}{2475}\)

⇒ \(\frac{100  - a}{100}\) = \(\frac{210375}{247500}\)

By calculating,

⇒ 15 = a

So, the second discount is 15%
