I got out of the
taxi and I was paying the fare. But the taxi driver could not give me change
for the rupee note. To my surprise I noticed my two friends Asha and Neesha
walking towards me. I requested them to give me exact change for my rupee not.
They searched their handbags and said “NO’
They both had
exactly Re 1.19 each in their handbag. But the denominations were such that
they could not give the exact change for a rupee.
What
denominations of change could they have had? They both, of course, had
different denominations.
Answer: I am showing below the possible
solutions. The important thing to remember about the problem is that P must be
less than four or it would be possible to make change for one rupee:
