As arun said, his weight is greater than 65 kg, and mother said, his weight cannot be greater than 68 kg.
then value will be 65<=68
It means value is 66,67,68.
then Required average = 66 + 67 + 68 = 201 = 67 kg.
then value will be 65<=68
It means value is 66,67,68.
then Required average = 66 + 67 + 68 = 201 = 67 kg.

His mother's view is that his weight cannot be greater than 68 kg
but she cant said that >=68
so the solution is 66+67/2=133/2=66.5
answer is none of these..

I got ans like tis way..., may i dont know whether is it correct r nt
view of arun avg=(65+72)/2=68.5
view of his brothers avg=(60+70)/2=65
view of his mother taken as=68
Therefore the avg of above three as=(68.5+65+68)/3=67
view of arun avg=(65+72)/2=68.5
view of his brothers avg=(60+70)/2=65
view of his mother taken as=68
Therefore the avg of above three as=(68.5+65+68)/3=67
