let marked price be x.

Given cost price = 900.

Given that gain = 10%.

SP = 900 + 10% of 900

     = 900 + 10/100 * 900

     = 900 + 90

     = 990.

Given that Discount = 10%.

SP = markedprice - 10% of 100

SP = x - 10/100 * 100

990 = x - 0.10x

990 = 0.9x

x = 1100.

The marked price = 1100.

Hope this help you..

Answer:

c.p=900

gain=10%

 =  \frac{10}{100}  \times 900 \\  = 90\% \\

s.p=C.P+GAIN

=900+90

=990

m.p = x \\

discount = 10\% \: on x \\  =  \frac{10x}{100} \\

s.p=m.p-discount

900 =  \frac{100x - 10x}{100} \\ 900 =  \frac{90x}{100}   \\ x =  \frac{900 \times 100}{90}  \\  = 1100
