Study the following bar graph that shows the number of students enrolled for different courses in institute A and B during 5 years, and answer the question that follows.
The number of students enrolled in A during 2014, 2016 and 2018 is what percentage of the total number of average students enrolled in B during the 5 years (correct to one decimal place) ?
Total number of students enrolled in A during 2014, 2016 and 2018 are :
$$\therefore\ 160+300+360=720$$
Average = $$\frac{sum\ of\ observation}{number\ of\ observation}$$
Total number of average students enrolled in B during 5 years are :
$$\frac{\left(225+360+375+325+225\right)}{5}=\ \frac{1510}{5}=302$$
Required percentage = $$\frac{720}{302}\times\ 100=\ 238.4\%$$
Hence, Option A is correct
