Rahul sold a watch to Sohan at a gain of 10% and Sohan sold it to Mohan at a loss of 10%. if Mohan paid rupees 990 for it find the price paid by Rahul
=> Price at which Rahul has sold it to Sohan = x + (10/100) * x, => Price at which Rahul has sold it to Sohan = 11x/10. => Price at which Sohan has sold it to Mohan = 11x/10 - (10/100) 11x/10, => Price at which Sohan has sold it to Mohan = 99x/100.
