The following bar graph shows the data of the production of an item (in thousand tonnes) from four different companies A, B, C and D during the years mentioned.
In the five years given, the average production is highest in company ......... and lowest in company .........., respectively.
Answer & explanation
Correct answer: option 2
In A ,
Average production of A = \(\frac{23 + 26 + 28 + 25+30}{5}\)
= \(\frac{ 132}{5}\)
= 26.4
In B ,
Average production of B = \(\frac{25+29+27+35+31}{5}\)
= \(\frac{ 147}{5}\)
= 49
In C ,
Average production of C = \(\frac{28+31+36+28+35}{5}\)
= \(\frac{ 158 }{5}\)
= 31.6
In D ,
Average production of D = \(\frac{32+35+40+46+50}{5}\)
= \(\frac{ 355}{5}\)
= 71
So , Average is highest of company D i.e. 71 and lowest of company A i.e. 26.4 .
Ans :- D ; A
