Question

Figure illustrates the information collected about the number of brothers of the boys in a certain group. What is the total number of boys in this group.

Answer 1

Given: The bar graph shows the number of boys having 1, 2, 3, 4, 5 and 6 brothers as 2, 5, 4, 8, 3 and 1, respectively.

Step-wise calculation:

Total = 2 + 5 + 4 + 8 + 3 + 1

= (2 + 5) + (4 + 8) + (3 + 1)

= 7 + 12 + 4

= 23

The total number of boys in the group is 23.
