Question

in a class 3/ 3rd students are boys with an avg score of 63 and girls avg score is 66 what is avg of entire class​

Answer 1

Answer:

Two possible answers as question is not clear.

If boys are one third of number in class

avg of whole class is 65

Step-by-step explanation:

And if boys are 2/3 of number in class

avg of whole class is 64

To make it simple take a class of 3 with 1 boy and 2 girls

so total marks are

63+66+66=195

ave =195/3=65

Case 2:

class has 2B and 1G

so total marks are

63+63+66=192

ave=192/3=64
