Solution

Let the first discount be x%.

Marked Price of shirt = ₹150

Price after first discount =100x100×Marked Price=100x100×150

Again 12.5% discount is given on the shirt after initial discount.

Price after second discount = ₹105

105=10012.5100×100x100×150

105=87.5100×100x100×150

100x=105 ×100 ×100150 × 87.5=80

x=10080=20

So, first discount is 20%.
