CP of 12 apples is equal to the SP of 9 apples and the discount on 10 ...
Given information:
- CP of 12 apples = SP of 9 apples
- Discount on 10 apples = Profit on 5 apples
To find: Percentage difference between CP and SP of apples
Solution:
Let's assume the CP of one apple to be x.
- CP of 12 apples = 12x
- SP of 9 apples = 9x
We know that CP > SP when there is a loss, and CP < sp="" when="" there="" is="" a="" profit.="" since="" here="" sp="" is="" less="" than="" cp,="" there="" is="" a="" />
Let the discount on 10 apples be y.
- Discount = Selling Price - Marked Price
- Discount on 10 apples = (10x - y) - (10x) = -y
This means that the discount is equal to the loss on 10 apples.
Let the profit on 5 apples be z.
- Profit = Selling Price - Cost Price
- Profit on 5 apples = (5x + z) - (5x) = z
This means that the profit is equal to the profit on 5 apples.
Now we can form two equations using the given information:
12x = 9x
10x - y = 5x + z
Solving these equations, we get:
x = 0 (not possible as CP cannot be zero)
y = 5x
z = 5x
This means that y and z are equal, and they represent a loss on 10 apples as well as profit on 5 apples. This is not possible, as there cannot be both loss and profit at the same time.
Therefore, the given information is inconsistent and the answer is "None of these".
