Q. The difference between a discount of 40% on 500 Rs. and two successive discounts of 36% and 4% on the same amount is :
Answer: 7.20 Rs.
Notes: Single equivalent discount of two successive discounts of 36% and 4%
$latex = 36+4-\frac{36\times 4}{100}&s=1$
= 40 - 1.44 = 38.56
Percentage difference = 40 - 38.56 = 1.44
∴ Required Difference =
$latex = 500\times \frac{1.44}{100} = 7.20 Rs.&s=1$
Hence option [A] is correct answer.
