<h2>Answer:</h2>

20.

<h2>Step-by-step explanation:</h2>

If 60% of the fish are red, then 40% are blue.

This means that the difference is 20%. As the difference between red and blue fish is given to you as 10, you know that 20% of the total is 10.

This means that 100% is 10 * 5, or 50 fish.

Because 40% of them are blue, 40% of 50 is 20, so there are 20 blue fish.

Answer:

20

Step-by-step explanation:

blue fish is x

red fish is (x+10).

Total fish = x+(x+10)=2x+10

60% = 0.6

So,

0.6=(x+10)/(2x+10)

⟹6(2x+10)=10(x+10)

⟹12x+60=10x+100

⟹2x=40

⟹x=20

answer is 20
