Each packet of washing powder carries a token and four tokens can be exchanged for a free packet. How many free packets will I receive
if I buy 64 packets?
Answer :
​(1) 64 packets have 64 tokens. Thus you can get 64/4=16 free packets.
(2) From the 16 packets you will get 16 tokens. These can be exchanged for another 16/4=4 packets.
(3) From the 4 packets you will get 4 tokens which can be exchanged for a free packet.
In total, you will get 16+4+1=21 free packets.

step-by-step explanation:

one day the were 5 ducks, and their king told them to multiply their kingdom. so each went their own seperate way and met 4 other ducks on their journey.

when the ducks returned to their kingdom, it was discovered that there were 5 groups of 5 ducks. when the kind counted the number of ducks in total (including the ones he sent out earlier) he counted 25.

therefore 5 times 5 is 25.
