Best answer

Given that C.P = 900 

There is a gain of 10% on C.P 

∴ Gain = 10% of ₹ 900

\(\frac {10\times900}{100}\) = ₹ 90

∴ S.P = C.P. gain 

= 900 + 90 

S.P = ₹990 …………….. (1) 

Let the marked price = ₹ x 

Discount on it = 10% on M.P = \(\frac {10x}{100}\)

∴ Selling Price = MP – Discount

∴ M.P = x = ₹1100
