Solution

The correct option is D 8% profit
Let the cost price of the article be Rs.100.
Let the list price of the article be"x".
Then, when the merchant offers a discount of 30%, the merchant will sell the article at x30% of x =70% of x =0.7x........(1)
The loss made by the merchant when she offers a discount of 30% is 16%.
Therefore, the merchant would have got 10016% of 100=Rs.84. when she offered a discount of 30%......(2)
Therefore, equating equations (1) and (2), we get
0.7x=84
or x=120.
If the list price is Rs.120 (our assumption of cost price is Rs.100), then when the merchant offers a discount of 10%, she will sell the article at
12010% of 120=Rs.108
As the cost price of the article was Rs.100 and the merchant gets Rs.108 while offering a discount of 10%, she will make a profit of 8%.
