​The following bar graph shows the production of a chocolate (in thousand tons) by three branches, X,Y and Z, of a dairy product company for 5 years. Based on the graph answer the question given below.

Which branch(s) of the company had the maximum average production for the 5 years?

Correct option is C

Given:

The production of chocolate (in thousand tons) by three branches (X, Y, and Z) over 5 years is given as follows:

Year 1 ,2 ,3 ,4 ,5

Branch X  40,50 ,35 ,55 , 50 

Branch Y 30, 35 , 45 , 45 , 55

Branch Z 50, 45, 40, 40 ,60 respectively.

Formula Used:

​$$\text{Average Production} = \frac{\text{Total Production over 5 years}}{5}$$​

Solution:

Calculate Total Production for Each Branch

Branch X: 40+50+35+55+50=230

Branch Y: 30+35+45+45+55=210

Branch Z: 50+45+40+40+60=235

Calculate Average Production

Branch X: $$\frac{230}{5} = 46$$​​

Branch Y: $$\frac{210}{5} = 42$$​​

Branch Z:$$\frac{235}{5} = 47$$​​

Maximum Average Production

The highest average production is 47, achieved by Branch Z.
