Question

Following are the marks (out of 50) obtain in mathematics of 10 students. 21, 40, 22, 21, 11, 30, 21, 9, 49​

Answer 1

Answer:

I think you're asking for the average.

so add all the numbers and divide by 10.

which is,

21+40+22+21+11+30+21+9+49

= 224

224 ÷ 10 = 22.4

so 22.4/50 is the average marks.
