There are three natural numbers A, B, and C. If we add A% of the average of B and C in the average of B and C, we get 33. If we add B% of the average of A and C in the average of A and C, we get 30, and If we add C% of the average of A and B in the average of A and B, we get 21. Find out these natural numbers.
1
A= 25, B = 30, C = 45
2
A = 30, B = 50, C = 40
3
A = 25, B = 20, C= 10
4
A = 10, B = 20, C=40
5
None of the above
