Correct answer: (A) 10%
After the first 20% discount, price = 1250*0.80=1000. The second discount reduces it to 900, so the second discount% = (1000-900)/1000*100 = 10%.

सही उत्तर: (A) 12%
पहली 20% छूट के बाद कीमत = 1250*0.80=1000 होती है। दूसरी छूट इसे 900 तक घटाती है, इसलिए दूसरी छूट% = (1000-900)/1000*100 = 10% है।
