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?
Answer & explanation
Correct answer: option 2
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%
