Riddle (simple arithmetic problem/illusion)
I have this small story (sorry about my bad English) : One man (M) took 25 dollar from man (A), and another 25 dollar from man (B), so now man (M) has 50 dollar. Man (M) spent 45 dollar from the 50 he had. The reminder he has now is 5 dollar. He used this reminder to give man(A) 1 dollar, and also give man(B) 1 dollar. That means as though that man (A) gave man(M) 24 dollar from the beginning, the same is for man(B), it seems he gave man(M) 24 dollar. Now man (M) has 3 dollar. Now, if we calculate the total: 24 + 24 + 3 =51, so we have 1 more dollar! From where it came? ?
And how can I show the trick by mathematical equations ?
