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 S in 2014 and 2017 is what percent of 90% of the total number of students appeared from school T in 2015, 2016 and 2017? (correct to one decimal place)

59.6

Number of students passed from school S in 2014 and 2017 =  273 + 247 = 520

Number of students appeared from school T in 2015, 2016 and 2017 = 300 + 320 + 350 = 970

90% of Number of students appeared from school T in 2015, 2016 and 2017 

=  \(\frac{9}{10}\) × 970

= 873

Required percentage =  \(\frac{520}{873}\) × 100

= 59.56%

= 59.6%   (correct to one decimal place)
