Study the following bar graph and answer the question given below.
The bar graph represents the total number of applications received for B.Sc. Mathematics by two different colleges A and B in 5 different years.
Find the difference between the average number of applications received by college A from 2014 to 2018 and the average number of applications received by college B from 2014 to 2018?
Answer & explanation
Correct answer: option 2
Average number of applications received by college A from 2014 to 2018
= ( \(\frac{220+160+250+180+160 }{5}\) )
= ( \(\frac{970 }{5}\) )
= 194
Average number of applications received by college B from 2014 to 2018
= ( \(\frac{150+240+170+150+240 }{5}\) )
= ( \(\frac{ 950 }{5}\) )
= 190
Difference b/w average number of applications received by A and B from 2014 to 2018
= 194 - 190
= 4
