Question of the Day

Tue 23 Jun 2020

A pet shop assistant is sent off to the wholesaler – by his boss – with £100. He is ordered to come back with exactly 100 animals and no change.
When he gets there, they only have three types of animal left:

Rabbits cost £8
Mice cost £3
Goldfish cost 50p

What is the lowest number of goldfish the assistant could have returned with having succeeded on his mission? He returns with at least one of each of the three types of animal.
