The given pie charts show the distribution of students in different streams in two schools, A and B. If school A has 1000 students and school B has 1200 students, what is the difference in the number of students in the science stream between the two schools?
180
From the pie charts, science is 30% in School A and 40% in School B.
Science students in School A = 30% of 1000 = 300.
Science students in School B = 40% of 1200 = 480.
Difference = 480 − 300 = 180.
Hence, the answer is 180.
