On an article with marked price Rs. 20000, a customer has a choice between three successive discounts of 20%, 20% and 10% and three successive discounts of 40%, 5% and 5%. By choosing the better offer, he can save:
(a) nothing
(b) Rs. 690
(c) Rs. 715
(d) Rs. 785
(e) None of these

• (b);(90% of 80% of 80% of Rs. 20000)=Rs. 11520.
  (95% of 95% of 60% of Rs. 20000)=Rs. 10830.
  Therefore, Saving=Rs. (11520-10830)=Rs. 690.
