Answer:

There were 3 children in the room

Explanation:

Let x be the number of children in the room

Since each child has 10 fingers including their thumbs, total number of fingers =10x

Each child has 2 ears so total number of ears = 2x

Since they had 24 more fingers than ears we get the equation:
10x - 2x = 24

8x = 24

x = 24/8 = 3
