A shopkeeper offers discount 50% + 50% on a shirt of M.R.P ₹800, find the selling price of the shirt.

₹200

Here,

50% + 50% means: First 50% discount will be calculated on listed price and then next 50% discount will be calculated on the discounted price.

Therefore,

Price after giving 1st 50% discount on M.R.P = 800 × 50% = Rs.400

Selling price after giving next 50% discount = 400 × 50% = Rs.200

or

We can use the formula of successive discount = 50% + 50% - \(\frac{50×50}{100}\)% = 100% - 25% = 75%

Selling price after giving 50% + 50% discount on M.R.P = 800 × (100 - 75)% = 800 × 25% = Rs.200
