The pie-chart shows the percentage-wise distribution of the number of students in five different schools P, Q, R, S and T. The total number of students in all five schools together is 10,500. Study the pie-chart and answer the question. The number of students in school R is what percent of the total number of students in schools Q and T together? Correct Answer 30%

Total number of students in school R = (12/100) × 10,500 = 1,260

Total number of students in school Q and T = {(16 + 24)/100} × 10,500 = 4200

⇒ Required percentage = (1260/4200) × 100 = 30%

∴ The number of students in school R is 30% of the total number of students in schools Q and T together
