of the students get grade A. 35% of the students get grade B.

The rest of the students get grade C. 10 students get grade C. Work out the number of

students who get grade A.​

Answer 1

Answer: 16 students got A.

Step-by-step explanation:

2/5 as a percentage is 40%

35% got B.

40%+35% = 75%

The rest is 10 students, 100 - 75 = 25

10 students = 25%

100 divided by 25 is 4

4 x 10 = 40

40 is total students.

40/100 got A.

40/100 x 40

= 16.

16 students got A.
