Number theory , number math

Solution: 

 

Total amount spent = Rs. 151.29

Men =?

 

 

Let there be ‘y’ number of men.

And each man spent  ‘y’ rupees ( it is given that each man will spend Rs equal to number of men).

Then total money spent by all ‘y’ men will be calculated by multiplying there number with spent amount by each men.

Total Money Spent = y\times y =y ^{2}

But ,

Toatl Money Spent = Rs. 151.29

\Rightarrow y ^{2}=151.29

\Rightarrow y =\sqrt{151.29}

\Rightarrow y =123
