Answer 1

Step-by-step explanation:

S.P. of a fan =Rs.710

Loss =Rs.40

C.P. = S.P. + Loss =Rs.710+Rs.40=Rs.750

If Gain =10%

Then S.P.=C.P.×(100+Gain%)÷100

= 750×(100+10)÷100

=Rs. 750×110÷100 =Rs.825

S.P. of a fan =Rs.710

Loss =Rs.40

C.P. = S.P. + Loss =Rs.710+Rs.40=Rs.750

If Gain =10%

$Then \: S.P.\: = \: \frac{C.P\times (100 + gain\%)}{100}$

$= \frac{(750 \times (100 + 10)}{100} = Rs. \frac{75 \times 110}{100}$

= ₹ 825.
