On an article with marked price Rs 20000, a customer has a choice between the successive discounts of 20%, 20% and 10% and three successive discounts of 40%, 5% and 5%. How much can he save by choosing the better offer ?

Answer»

M.P. = Rs 20000

S.P. after choosing 1st set of successive discounts = 80% of 80% of 90% of Rs 20000

\(\frac{80}{100}\) x \(\frac{80}{100}\) x \(\frac{90}{100}\) x Rs 20000 = Rs 11520

S.P. after choosing 2nd set of successive discounts = 60 % of 95% of 95% of Rs 20000

\(\frac{60}{100}\) x \(\frac{95}{100}\)\(\frac{95}{100}\) x Rs 20000 = Rs 10830

\(\therefore\) The second offer is better and the customer can save (Rs 11520 – Rs 10830) = Rs 690.
