प्रश्न

Find the single discount (as a percent) equivalent to successive discounts of:
60% and 80%

बेरीज

उत्तर

Successive discounts = 60% and 80%

Let M.P. = ₹100

∴ S.P. after two discounts,

`=₹(100(100-60)xx(100-80))/(100xx100)`

`=₹(100xx40xx20)/(100xx100)=₹8`

∴ Total discount = ₹100 − 8 = ₹92

∴ Single discount = 92%
