The given pie charts show the distribution of students of graduate and postgraduate levels in five different institutes. P,Q, R, S and T, in a town. Study the pie charts and answer the question that follows.

(i) Total number of students of graduate level in five different institutes = 12400

(ii) Total number of students of post graduate level in five different institutes = 8000

The number of students in graduate level in institute S is approximately what percentage more than the number of students in post graduate level in institute S? (correct to one decimal place)

72.2%

Number of students in graduate level in institute S = \(\frac{20 }{100}\) × 12400

= \(\frac{1 }{5}\) × 12400

= 2480

Number of students in post graduate level in institute S = \(\frac{18 }{100}\) × 8000

= 1440

Required percentage = \(\frac{2480 - 1440  }{1440}\) × 100

= \(\frac{ 1040 }{1440}\) × 100

= 72.2%
