How many children were there in the room? n a room. First, they counted all their fingers (including thumbs), then they counted all their ears and found that altogether they had 24 more fingers than ears. How many children were there in the room?

Answer 1

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
