Study the following table and answer the question:
Number of students Appeared (A) and Passed (P) in an annual examination from four schools Q, R, S & T in five years (2014 to 2018)

The total number of students passed from school Q in 2014 and 2018 is what percent less than the total number of students appeared from schools R and S in 2017?

30%

Passed students of Q in 2014 & 2018 = 240 + 320 = 560

Appeared students of R & S in 2017 = 420 + 380 = 800

Required percentage = \(\frac{800 - 560}{800}\) × 100

= \(\frac{240}{800}\) × 100

= 30%
