Question

find a single discount equivakent to three successive discount of 10% ,5% and 4%​

Answer 1

Answer:

17.92%

Explanation:

Let us assume we have 100 units

After first discount which is of 10% we are left with 90 units

Then next discount is 5%

therefore, 5% of 90 which is 4.5

now we are left with 90 - 4.5 = 85.5

Then next discount is of 4%

therefore, 4% of 85.5 which is 3.42

now we are left with 85.5 - 3.42 = 82.08

Hence total discount is 100 - 82.08 = 17.92

hence (17.92/100)×100 = 17.92%
