A shopkeeper gives an initial discount of 15% on the marked price of the sewing machine. He then gives 8% additional discount on the discounted price. If the final sale price of the machine is ₹1,564, find the marked price.

Show answer & explanation

Correct answer: C

Explanation

The correct answer is Option 3 i.e. ₹2,000.

Let marked price = ₹x

⇒ x×85100×92100=1564x\times{85\over100}\times{92\over100}=1564

⇒ x×1720×2325=1564x\times{17\over20}\times{23\over25}=1564

⇒ x = 4 × 25 × 20 = 2000
