There are oranges that are ¥90 and apples that are ¥150.
When you buy a total of 15 of them, your total cost is ¥1890.
How many oranges and apples did you buy?

Step-by-step explanation:

If 15 oranges were bought,

the total cost would be 15 * ¥90 = ¥1350.

¥1890 - ¥1350 = ¥540.

For every orange that switches to an apple,

the cost increases by ¥150 - ¥90 = ¥60.

Number of apples = ¥540 / ¥60 = 9.

Therefore there are 6 oranges and 9 apples.

Answer:

6 oranges and 9 apples.

Step-by-step explanation:

Let the number of oranges be x then the number of apples = 15 - x.

So  90x +  150(15 - x) = 1890

90x - 150x + 2250 = 1890

-60x = -360

x = 6

and number of apples = 15 - 6

So it's 6 oranges and 9 apples.
