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.) By what percentage is the average sales turnover of all the companies combined in 2015-2016 more than the average sales turnover of the companies A, C and E in 2014-2015 (to the nearest whole number)?

By what percentage is the average sales turnover of all the companies combined in 2015-2016 more than the average sales turnover of the companies A, C and E in 2014-2015 (to the nearest whole number)? Correct Answer 16

Calculation:

Sales turnover of all the companies in 2015-16 = (1250 + 1125 + 900 + 1220 + 1290)

⇒ 5785

Average sales turnover = 5785/5

⇒ 1157

Sales turnover of the companies A, C and E in 2014-15 = (1060 + 850 + 1080)

⇒ 2990

Average sales turnover = 2990/3

⇒ 996.66

Required percentage =  × 100

⇒ (160.34/996.66) × 100

⇒ 16.08 ≈ 16

∴ Required percentage is 16
