Question

5. What is the single discount equivalent to two successive discounts of 50% and 50%?
​

Answer 1

Answer:

75%

Step-by-step explanation:

Let x be some arbitrary amount.

Then two successive discount of 50 % amounts x to

[(x - (50 % of x) )] - (50 % of (x - (50 % of x) )

= [x - 0.5x] - [ 0.5 * ( x -0.5x) ]

=0.5x - 0.5x +0.25x

=0.25x

Therefore discount

= (1-0.25) * 100

=75%
