Question

find the single discount which is equivalent to two successive discount of 20% and 15%​

Answer 1

Mp = 100

1st discount = 20% of 100 = 20

since, 100 - 20 = 80

2nd discount = 5% if 80 = 4

sp = 80-4 = 76

Single Equivalent Discount  = MP - SP = 100 -76 = 24

Since,The discount of 24 is on 100

Required single discount  = 24%
