Number (patterns): Monkey Thief
The Problem
In the city Jaipur, there was a very long washing line. Pegged to this washing line, were Mr Sharma’s shirts. All of the shirts on the line were either red, yellow, green or blue.There were 76 shirts in total. Mr Sharma was quite fussy about the order by which they were pegged to the line. You can see this order (from left to right) and the start of the washing line in the picture opposite.
One afternoon, a mischievous rhesus macaque (called Hanu) stole the 68th shirt on the line.
What was the colour of the shirt that Hanu stole? How do you know?
Did you know?
Sadly, animals (including monkeys) were sent into space before humans. The first monkey sent into space by NASA was a rhesus macaque called Albert.
Visualising the Problem and Getting Started
Betty said, “To find the colour of the 68th shirt, I will need to draw this number of shirts.” Do you agree with Betty?
