Answer 1

Answer:

1) so let the cost price of mobile to Pratik is X.

so,C.P of Pratik =s.p × 100/(100+p%)

=11040×100/(100+20)

=1104000/120

=Rs.9200

2) Sunayana brought the phone and sold it to

Pratik at 8% loss.

So let the cost of phone to Sunayana is Y.

so, C.P of Sunayana = s.p × 100(100-L%)

=9200*100(100-8)

=920000/92

=10000
