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
