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
