Question

A single discount equivalent to successive discount of 30%, 20% and
10% is-
​

Answer 1

Answer:

49 2/3%

Step-by-step explanation:

let mp = 100

30% of 100 =30

remaining = 100 - 30 =70

20% of 70 =14

remaining = 70 - 14 = 56

10% of 56 =5.6

remaining = 56 - 5.6 =50.4

total discount allowed = (100-50.4) = 49.6

hence , the required single discount = 49.6%
