My Son Is Naughty

Jack and Ray were at the rugby. Ray’s team was winning 
so Jack decided to give Ray a problem to deflate his ego a 
bit. So Jack said “Did you know that today is my three 
sons’ birthday?” “How old are they?” Ray asked taking 
the bite. “I’ll give you a hint. The product of their ages is 
36 and the sum of their ages is 13,” Jack replied. “That’s 
no help,” said Ray. So Jack weakened and gave him 
another clue. “O.K. My youngest son is very naughty.”
“Nothing to it,” exclaimed Ray and he told Jack the 
correct ages of his sons.

The Rock Pool

Untitled from Team 5 PES on Vimeo.
Some octopuses, some fish and a few 
mermaids were happily frolicking in a rock 
pool. Altogether there were 38 arms, 24 eyes 
and 8 tails all swimming in the pool. 
How many mermaids were there?

We were given a task to find how many of each creatures there were from the question we had to answer. Mermaids, Octopus and Fishes were having fun in the rock pool. So there were 38 arms, 24 eyes and 8 tails.  We first started by using the easiest body part which were the eyes. We had to answer the question of how many Mermaids that were in the rock pool.  Each creature had 2 eyes so we divided 24 by 2 which was 12 so we now know that there were 12 creatures all together. Next we started which the tails. There were 8 tails and 2 of the creatures which were mermaids and fish with them. Now we know that there are only 8 creatures with tails and obviously octopuses don’t have tails so there is 4 Octopuses because there were 4 left from the 12. But to make us sure that there were 4 Octopuses, we next used the arms as part of our second body part. Octopus have 8 arms so we used 8 (Octopuses) times 4 which was 32 and 38-32 equal 6. Fish don’t have arms and of course Mermaid’s do so we divided 6 by 2 which was 3. So far we’ve got 4 Octopus and 3 Mermaids which also answers the question of how many Mermaids there were. Still, we’ve got 5 more tails which is for the fishes because three of the tails have been subtracted and used for the Mermaid. 3 Mermaids and 5 more tails meaning there were 5 fishes.
So 5 (fishes) + 3 (mermaids) + 4 (Octopus) = 12

Restaurant Question

Max Pizza from Team 5 PES on Vimeo.
The Pizza Place in my town has three
tables of the same size. The Chicken
N Chips restaurant has four of the
same sort of table.
The Chicken N Chips can just seat 24
people. How many people can The
Pizza Place seat?
Now a third of the seats at The Chicken N Chips were
empty and a half of the places at The Pizza Place were
empty. If 18 more people wanted to eat out, how many
would have to be turned away from the two restaurants?
