Performance of 1800 students in grades has been shown in the following pie chart. In which two grades taken together is the number of students 54 less than the number of students in grades B and E taken together? Correct Answer C and E

Given:

The performance of 1800 students in grades has been shown in the following pie chart.

Calculation:

Total percentage of grades B and E = 27% + 8% = 35%

Here, (54/1800) × 100 = 3%

Then, 54 students of 1800 is 3% students

We have to find the sum of two groups in which the sum of percentage = 35% - 3% = 32%

The percentage of students in Grade C = 24%

The percentage of students in Grade E = 8%

The total percentage of Grade C and E = 24% + 8% = 32%

∴ The number of students is 54 less than the number of students in grades B and E taken together in Grade C and E
