Answer:

Cp=100/100+gain%×Sp

=100/100+5×1260

=100/105×1260

=Rs.1200

1) Cp=100/100+gain%×Sp

=100/100+5×1250

=100/105×1250

=1, 312.5

2) Cp=100/100+gain%×Sp

=100/100+5×1100

=100/105×1100

=1155

3) Cp=100/100+gain%×Sp

=100/100+5×1200

=100/105×1200

=1260

4) Cp=100/100+gain%×Sp

=100/100+5×1212

=100/105×1212

=1272.6
