Question
For an electric bill for ₹50,000, what is the
difference between a discount of 30% and two successive discounts of 26% and 5%?Solution
Here, Bill. = Rs50,000 and discount = 30% As we know that. S.P. =(1-d/100) x M.P. S.P. (1-30/100) × 50000 = 70/100 x 50000 S.P. = Rs35,000 Now, d1 = 26%, d2 = 5% and, M.P. Rs50,000 S.P. (1-26/100) × (1-6/100) × 50000 = 74/100 × 95/100 × 50000 S.P. = Rs 35150 The difference both cases = Rs (35150 - 35,000) = Rs150.
