Some of weights=8*100=800
Now we do know just the above
However, the weights could be 8 of 50 or 7 of 50 and 250 or ANy combination that gives you 8 numbers which average is 800
D is the answer

Answer is D,
since any student can't be exactly 100, lets take the following example
98,98,98,98,102,102,102,102
here both are equal in number,
but lets take another scenario
1,98,98,98,102,102,301
simply there are n number of ways to divide 800 into 10 numbers
so answer D
