How many blueberries do you see? I counted 15.

Did you get it right?

Count only the real blueberries.

The Answer

There are 15 blueberries.

Here is why

1. Count 7 blueberries in the bowl.
2. Count 4 blueberries in the paper cup.
3. Count 4 loose blueberries on the cloth.
4. 7 + 4 + 4 = 15.

Why people miss it

Blue flowers and patterned cloth can distract from the real blueberries.

Did this one fool you at first glance?
