Answer 1

The total number of people in the room is 14

Explanation:

The ratio of the number of women to the number of men to the number of children in a room is 5:2:7

So, there are

• 5 women
• 2 men
• 7 children

(1) The total number of women and children in the room is 12.

5 women and 7 children=12

(2) There are fewer than 4 men in the room.

There are 2 men , that´s fewer than 4

So, the total number of people is 5+2+7= 14
