(correct to one decimal place) Correct Answer 59.6

Calculation:

The total number of students passed from school S in 2014 and 2017 = (273 + 247)

⇒ 520

The total number of students appeared from school T in 2015, 2016 and 2017 = (300 + 320 + 350)

⇒ 970

Now,

According to the question

90% of the total number of students appeared from school T in 2015, 2016 and 2017 = (90% of 970)

⇒ (90/100 × 970)

⇒ 873

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 = (520/873 × 100)

⇒ 59.564% ~ 59.6%

∴ The required percentage is 59.6
