A,B,C are having some marbles with each of them.
A has given B and C the same number of marbles each of them already have.
Then, B gave C and A the same number of marbles they already have.
Then C gave A and B the same number of marbles they already have.
At the end A, B, and C have equal number of marbles.
11. If x,y,z are the marbles initially with A,B,C respectively,
then the number of marbles B has at the end are ____
1] 2(x-y-z) 2] 4(x-y-z) 3] 2(3y-x-z)
4] x + y-z
12. If the total number of marbles are 72, then the number of marbles with A at the starting were
1] 20 2] 30
3] 32 4] 39
