#562 - Reach Top Riddle
An ape is trying to climb on a pole that is 60 feet high. Due to the slippery surface, the ape climbs 3 feet in a minute only to slip back 2 feet.
How much time do you think the monkey will take to reach the top of the pole?
Hint: The answer is not sixty minutes.
The ape will be able to reach the top in 58 minutes.
Since the ape slips back two feet after climbing 3 feet every minute, he will reach 57 feet in 57 minutes. Now the remaining distance is 3 feet and the ape will take 1 more minute to reach there. He wont slip back because he has already reached the top.

#564 - Split Money Pizza Maths Puzzle
Rihana, Peeta, and Logan order a pizza for $10. Out of the three, Rihana and Peeta were quite hungry and ate 6 slices a piece, while Logan had just 2 slices.
Now, they want to split the cost among them fairly but due to the lack of change, they decide to round of the cost to the nearest possible dollar.
Can you find out the fair way which should be used to split the money?
What if the pizza was worth $11?
If we assume that Rihana and Peeta pay the same amount, they can decide with "rock, paper, scissor" to determine who will pay the extra dollar. Any other method may be used as well. Suppose that Rihana pays $1 extra.
In this manner, Rihana pays $5, Peeta pays $4 and Logan pays $2.
If the pizza would have cost $11, this method will then prove to be great because both Rihana and Peeta will pay $5 each and Logan will pay $1. This will keep the offset same as previous. Rihana is paying 6% more, Peeta is paying 15% more and Logan is paying 27% more.
#566 - Find Ages Riddle
Priyanka and Rubina are having a conversation.
Priyanka: I am definitely not over 30.
Rubina: I am 28 and you are surely 5 years older to me at least.
Priyanka: No, you are at least 29.
You are told that both of them are lying throughout in the conversation. Can you find their respective ages?
We know that both of them were lying in all their statements. Thus we can assume the opposite of what they said:
Priyanka: I am definitely over 30.
Rubina: I am not 28 and you are at most 4 years older to me.
Priyanka: You are at most 28.
Now we can conclude from the first statement that Priyanka is 31 years old at least. From the second and third statement, we can conclude that Rubina is at most 28 years old. Therefore, the possible ages of Priyanka and Rubina can be:
Priyanka: 31, 32, 33, 34, 35, 36...
Rubina: 22, 23, 24, 25, 26, 27...
If we look at the second statement again, we know the difference between their ages is a maximum of 4 years.
Therefore, Priyanka age is 31 years while Rubina age is 27.
