​The following bar graph shows the profit made by a software company (in million $) from 2012 to 2018. Based on the bar graph answer the question given below.

What is the ratio of the number of years in which the profits are above average to those in which the profits are below average?

Correct option is B

Given: 

Maximum profit year = 2013-14 = 380

Minimum profit year = 2014-15 = 290

Formula Used:

Average = $$\frac{\text{Number of observations}}{\text{Sum of all observations}}$$

Solution:

Maximum profit year = 2013-14 = 380

Minimum profit year = 2014-15 = 290

Average = $$\frac{300+380+290+310+350}{5}$$​ = 326

For ,
 = Maximum profit year - Average ,   

= 380-326= 54,     

For,

= Average - Minimum profit year

= 326-290 =36

Now, ratio

{(Average - Minimum profit year):(Maximum profit year - Average)}

=  36 : 54 = 2 : 3
