Cough syrup of three different flavours - A, Band C (in lakh bottles) manufactured by a medicine company over a period of five years from 2010 to 2014 has been shown in the bar graph.
The ratio of the average production of all flavours in 2012 to the difference of the average production of flavor A in 2012, 2013 and 2014 and the average production of flavour C in 2012, 2013 and 2014 is :
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 11 : 3
Ratio of the average production of all flavors in 2012 = (50 + 50 + 65) = 165
Average production of all the flavors = 165/3 = 55
Ratio of average production of flavor A in 2012, 2013 and 2014 = (50 + 45 + 75) =170
Average production of flavor A in 2012, 2013 and 2014 = 170/3 = 56.66
Ratio of average production of flavor C in 2012, 2013 and 2014 = (65 + 70 + 80)
⇒ 215
Average production of flavor C in 2012, 2013 and 2014 = 215/3 = 71.66
The difference of the average production of flavor A in 2012, 2013, and 2014 and the average production of flavor C in 2012, 2013 and 2014 = (71.66 – 56.66) = 15
required ratio = 55 : 15
⇒ 11 : 3
