Answer 1

(Total cost - cost of apples) `xx 2/3`

Explanation:

Although there seem to be three variables - being the cost of each type of fruit, there is actually only one unknown.

The cost of the oranges is double the cost of the grapes.
Let the cost of the grapes be `x`.
The cost of the oranges is therefore `2x`

The cost of the grapes and oranges together is `3x`

If you know the cost of the apples, subtract that from the total cost of all the fruit.
The answer is the cost of the grapes and the oranges.`3x`

Divide by 3 to find the cost of the grapes `x`.
Multiply by 2 to find the cost of the oranges.

(Total cost - cost of apples) `xx 2/3`
