In the Puzzle Fry criminal court A man was being accused of having stolen certain valuable jewels and trying to run away with them, when he was caught by a smart police officer who overtook him.
In cross examination the lawyer for accused asked the police officer how he could catch up with the accused who was already seven steps ahead of him, when he started to run after him. ‘Yes Sir.’ The officer replied. ‘He takes eight steps to every five of mine !
‘But then officer,’ interrogated the lawyer, ‘how did you ever catch him. if that was the case?’
‘That’s easily explained sir,’ replied the officer, I got a longer stride… two of my steps equal in length to his five. So the number of steps 1 required were fewer than his. and this brought me to the spot where I captured him.’
A member of the jury, who was particularly good at quick calculations did some checking and figured out the number of steps the police officer must have taken.
Can you also find out how many steps the officer needed to catch up with the thief?View SolutionSubmit Solution- 1,646.6K views

Though I did not remember the exact number I did remember that the bus number bad a certain peculiarity about it. The number plate showed the bus number as a perfect square and also if the plate was turned upside down.? the number would still be a perfect square—of course it was not?
