Urrrm, please this question has been shared severally in so many social media......you might have come across it before. But i jst can't stop solving the problem.

You saw a book and you had no cash with you, and this book is sold for #97, you decided to borrow 50bucks from mum and another 50bucks from big bro(100bucks altogether). You later bought this book at the price of 97bucks and recieved #3 change, you decided to give mum #1 and owe her #49 and also gave big bro #1 to owe him #49 too, you kept #1 to ur self.

Now, 49+49=98+the #1 you gave mum and the #1 you gave big bro added to the #1 you kept for urself equals 101. Question is, where is 1 naira coming from? Think people.......

no idea my dear
i no go school reach you

God is the great provider... ...

Hehehehe, na serious case ohh, abeg make una help me nah

maximale: Simple.
50 (mum)+50(bro)=97(book)+3(change)
therefore:
97+3-2(return N1 each) = 50-1(return 2 mom) + 50-1(return 2 bro)
thus:
97+1=49+49
conclusion:
if 1 moves to the otherside, it must become -1 and not remain +1. Also if u add 1 to one side, u mst add 1 to the otherside too. The puzzle ddnt obey both laws so the puzzle is mathematically incorrect

Lmao....dude seriously i didn't understnd any of this.......break it down more. You still dey speak mathematical language, abi u be proffessor?
