Operation: Money Tracking
An elementary student was asked to solve a certain problem by his teacher. The problem was all about counting money. The teacher said, "If I have 100$ in my pocket and I gave half of it to you but then you gave back triple the half I gave to you......" The student asserted directly, "Sir, you got 200$ in your hand then!" The teacher replied with a smile, "That is absolutely correct, but... what if my pocket money was 25$ all along and following the same process, how much money would be in my hand?"

1 solution
If the teacher had 100, the value after all the giving and taking of money would be 200.
Similarly, if the teacher had 25, we just multiply it by 2 to get the answer, which is 50.
