Direction: Sales of books (in thousands} from six branches (B1, B2, B3, B4, B5, B6) of a publishing company are given below. Study the graph and answer the following questions.
-
If all the six branches are divided into three groups such that each group has equal performance on selling books, then the minimum difference of the number of books (in thousands) sold by the two members of any group is
-
- 20
- 10
- 15
- 5
Correct Option: B
As per the given bar graph in question , we have
B1 + B4 = B2 + B6 = B3 + B5 = 100000
B3 – B5 = 55 – 45 = 10 thousand
B4 – B1 = 80 – 20 = 60 thousand
B6 – B2 = 60 – 40 = 20 thousand
∴ Minimum difference = 10
