Hi,

The answer here will be (B).

Consider the Cost Price of a single apple to be 'x'. Therefore, the Selling Price for a single apple will be 2.25x.

For 100 apples, the SP will be 2.25x * 100 = 225x - (i)

For 200 apples, the SP will be 2.25x * 200 = 450x, or the double of (i).

But there is a discount of 10% as well. Therefore, the value will become 450x * 0.9=405x.

405x > 225x, therefore the answer here is (B).

These calculations may become easier for you if you assume a value of each apple to be Rs. 100.

For instance, Option A will result in $225, while Option B will be a discount of 10% on double the amount obtained in Option A, i.e., a 10% discount on $450, which is $405. Since, 405 is greater than 225, the answer will be (B).

Can you please explain why selling at 125% of his cost isn't equal to 1.25? If it cost him 1$ to purchase the apple, isn't 125% of $1 = $1.25?
