The given graph shows the number of students who passed SSC in two institutes (P and Q) during four years.
What is the difference between the average number of students who passed in institute P in 2015 and 2016 and that in institute Q in 20 17 and 2018?
Answer & explanation
Correct answer: option 3
Average number of students passed from P in 2015 & 2016 = \(\frac{200+250}{2}\)
= 225
Average number of students passed from Q in 2017 & 2018 = \(\frac{150 + 50 }{2}\)
= 100
Required difference = 225 - 100
= 125
