IMO : A
Revenue = Selling Price * Sales
Let us consider Revenue = 99
SP = 11
Sales = 9
St 1: When the salesman reduces the selling price of the product by 9.09%, the sales increase by 11.11%
9.09% = 1/11
11.11% = 1/9
SP is reduced by 1/11 = 11- 11* \(\frac{1}{11}\)
= 10(reduced price)
Sales increase by 1/9 = 9+9*\(\frac{1}{9}\)
= 10
Thus new revenue = 10*10 =100
No chance
Hence Suff
St 2: The number of units of the product sold before the change in price was 990
Nothing is given about the selling price before and after
Nothing is given Sales after change in price
Hence not suff
