Answer 1

Answer:    A,D,E

Step-by-step explanation:

Answer 2

The cost price of a swim-suit, C.P.=$8

Option 1:

If the selling price is marked up by 25%, the new selling price is

$S.P.=C.P.+C.P.\times 25\%$

$=8+8\times\frac{25}{100}$

=8+2

=10

So, the selling price will be $10 which is the same as the mentioned selling price.

Hence, this option is correct.

Option 2:

If the selling price is marked up by 40%, the new selling price is

$S.P.=C.P.+C.P.\times 40\%$

$=8+8\times\frac{40}{100}$

=8+3.20

=11.20

So, the selling price will be $11.20 which is not the same as the mentioned selling price, $7.50.

Hence, this option is wrong.

Option 3:

If the selling price is marked up by 55%, the new selling price is

$S.P.=C.P.+C.P.\times 55\%$

$=8+8\times\frac{55}{100}$

=8+4.40

=12.40

So, the selling price will be $12.40 which is not the same as the mentioned selling price, $5.50.

Hence, this option is wrong.

Option 4:

If the selling price is marked up by 70%, the new selling price is

$S.P.=C.P.+C.P.\times 70\%$

$=8+8\times\frac{70}{100}$

=8+5.60

=13.60

So, the selling price will be $13.60 which is the same as the mentioned selling price.

Hence, this option is correct.

Option 5:

If the selling price is marked up by 75%, the new selling price is

$S.P.=C.P.+C.P.\times 75\%$

$=8+8\times\frac{75}{100}$

=8+6

=14

So, the selling price will be $14 which is the same as the mentioned selling price.

Hence, this option is correct.
