The answer is E.
This can be solved logically: the question asks about absolute numbers, but the statements only give us percentages - insufficient!

Theoretically, the answer would be E because all the given info is ratios, no definite numerical values.

however, I find myself in front of an illogical finding upon combining the two statements:

John = \(\frac{6}{5}\) Tom = \((\frac{6}{5})^2\) Jane.

as John = Tom + Jane + More

Then More = John - \(\frac{5}{6}\) John - \(\frac{25}{36}\) John = \(-\frac{19}{36}\) John ---- > which is a negative value contradicting with the mentioned fact that John has more coins than both of Tom and Jane

Am I wrong?

(if so, changing the '20%'s to '200%'s would make it more plausible)
