The difference between a discount of 40% on $ 500 and two successive discounts of 36%, 4% on the same amount is :
-
- $ 0
- $ 2
- $ 1.93
- $ 7.20
Correct Option: D
Single equivalent discount for 36% and 4% i.e.
Here , a = 36% and b = 4%
Equivalent discount =  36 + 4 - | 36 x 4 |  % |
| 100 |
Equivalent discount = ( 40 - 1.44 )% = 38.56%
Therefore, required difference = 1.44% of 500
| = | x 500 = $ 7.20 | 100 |
