To be particular in that problem, we also require the composition of air. I assumed it to be $$N_{2}$$ and $$O_{2}$$ in 4:1 ratio. The person should also give the values like $$g$$, $$R$$ and temperature . So, the error was due to my own assumptions.

I will tell yoy a funny thing. There was once a question in which the probability was asked, you know it will be 0.something. In the answer box, it was written 'decimals OK', so I simply wrote 0 as the answer. I don't know why, but it went wrong!
