Study the given bar graph and answer the question that follows.
The given bar graph represents the Sales Turnover (in Rs. crore) of five automobile companies A, B, C, D and E during 2014-2015 and 2015-2016. The X - axis represents the Companies and the Y - axis shows the Sales Turnover (in Rs. crore).
(The data shown here is only for mathematical exercise. They do not represent the actual figures of the company.)
If there was an increase of 25% in the average of the sales turnover of all the companies together in 2014-2015 from that in 2013-2014, then what was the average (in Rs crore up to two decimal places) of the sales turnover of all the companies together in 2013 - 2014?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 848.64
Given :
Average sales increased by 25% in 2014 - 15 from that in 2013 - 14.
Formula used :
Average of numbers = (Sum of observations)/(Number of observations)
Calculations :
Average sales turnover in 2014 to 2015
⇒ (1060 + 954 + 850 + 1360 + 1080)/5
⇒ 1060.8
⇒ 125% of sales of 2013 - 2014 = average sales of 2014 - 2015
⇒ 125 % of sales of 2013 - 14 = 1060.8
Average sales of 2013 - 14 = 1060.8 × (100/125)
⇒ 1060.8 × (4/5)
⇒ 4243.2/5
⇒ 848.64
