The performance of 1800 students in grades has been shown in the following pie chart.
How many more students have obtained grade B than those who have obtained grade C?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 54
Number of students have obtained grade B than those who have obtained grade C = 27% of 1800 - 24% of 1800
⇒ 3% of 1800 = (3/100) × 1800 = 3 × 18 = 54
