Use reasoning to lead to the answer of the following question:
A young girl pours 23 blue beads and 16 yellow beads into a bowl. She divides the total into 3 equal parts, removes some beads from each part, and doubles the rest to have 6 beads in each part now. How many beads were removed from each part?

10
There are 23 + 16 = 39 beads in the bowl.

Dividing them into 3 equal parts give 39 / 3 = 13 beads each.

Before doubling the number of beads, she had 6 / 2 = 3 beads left in each part.

Therefore she had removed 13 - 3 = 10 beads from each part.

.

Therefore, the answer is 10
