Question

Which is more favourable to a buyer and by how much rs3,000 with 14% discount or the same amountwith two successive discounts of 10% and 5%?​

Answer 1

Answer:

ok so , 3000 × 100-14/100 = 2,580 , now 2 successive discounts of 10 and 5 percent is , to ffind out use formulae x + y + xy/100 and as discount is of - use - instead of + so answer is -5-10 +50/100 = -15+.5 = -14.5

means two successive discounts of 5 and 10 is 14.5 now

3000 ×100-14.5/100 = 2,565 means this option is good , and it gives a rs.15(2580-2565) more discount

hope this helps
