Answer 1

Answer:

let the M.P be 100

first discount=20% of mp

=20/100*100

=20

mp after first discount

=100-20=80

now the mp =80,second discount=10% of mp

=10/100*80

=8

mp after second discount=80-8=72

now the mp after second discount=72

third discount=5% of mp

=5/100*72

=3.6

mp after third discount=72-3.6

=68.4

the single discount equivalent to given successive discount=(100-68.4)%

=31.6%
