Study the following table and answer the question:-

Numbers of students appeared (A) and passed (P) in an annual examination from four schools P, Q, R and S in five years (2014 to 2018).

The difference between the average no. of students passed from school R in 2014 to 2016 and the no. of students passed from school Q in 2014 is x.  The value of x is?

67

No. of students passed in R in 2014 to 2016 = 275 + 280 + 264 = 819

Avg. = \(\frac{819}{3}\) = 273

No. of students passed from Q in 2014 = 340

Difference (x) = 340 - 273 = 67
