Question

A single discount equivalent to the discount series of 20% 10% and 5% is?​

Answer 1

Step-by-step explanation:

let the price be 100

so first discount=20/100*100=20

price=100-20=80

second discount=10/100*80=8

so price =80-8=72

third discount =5/100*72

price =72-3.6=68.4

difference =100-68.4=31.6
