Hi,

If A gives 6 marbles to B, A will have twice marbles as B.
If A gives 10 marbles to B, A will have thrice marbles as B.
Find out how many marbles does B have at first?

Thanks.

Hey <yenny>,

I appreciate if you can check the question again. I think there is something wrong with one of the "IF" statements in the question.

Thank you.

Cheers,
Edward

Hey <yenny> and all ,

If there are similar questions to this, one can make use of the <Unchanged Total> concept to solve as both cases are <Internal Transfer> processes. Hence, total units in the end comparison of both cases are the same.

Another method is to use the <Before> and <After> concept.

Cheers,
Edward
