Question 58

A buys an article at ₹1800 and sells it after giving two successive discounts of 10% and 20%. What will be the selling price (in ₹) of the article?

Solution

A buys an article at ₹1800 and sells it after giving two successive discounts of 10% and 20%.

the selling price of the article = ₹1800 of (100-10)% of (100-20)%

= ₹1800 of 90% of 80%

= $$1800\times\frac{90}{100}\times\frac{80}{100}$$

= $$18\times72$$

= ₹1296
