The bar graph given below shows the data of the production of paper (in lakh tonnes) by three different companies P, Q and R over the years.
What is the ratio of the average production by company P during the period 2010 to 2013 to the average production by company R during the same period?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 34:35.
average production by company P = (35 + 50 + 30 + 55)/4 = 170/4
average production by company R = (40 + 45 + 50 + 40)/4 = 175/4
Ratio = 170:175 = 34:35
