A single discount equivalent to three successive discounts
of 20%, 25% and 10% is
a) 55% b) 50% c)48% d)46%

plz specify the method... thanks

Answer Posted / isha trivedi

100-20=80
100-25=75
100-90=90

now assume that the discount is given out of 100

so 80*75*90/100*100*100=0.54
so the one equivalent discount will be 1-0.54=0.46x100=46%
