I think that this may be difficult; the first thing to ask is why not do all the paper to Indian Railway practice.
You must understand that I know very little about this (HELP SOMEONE?), but I have just a little knowledge (which is always a dangerous thing!......).
I am guessing but perhaps the practice you are familiar with is broadly to mechanical signalling principles, but with colour lights rather than semaphore signals and a few additional signals to break up long sections, but not what from the UK we would call true "Multiple Aspect Signalling".
If I am right then you would place your distant signals according to braking from the first stop signal and the capacity of the line would be determined by the length of the block section from one station / signalbox to the next, and the two factors do not interrelate in the same manner.
I guess therefore that you may be unable to answer this part of the question paper to the Indian practice with which you are familiar; a headway of 2 minutes may just not be possible on the system for which you wish to answer the question.
If this were the case, then provided you explain this briefly in your answer, I think that your proposal simply must be acceptable to the IRSE- after all it is hard to see what else you could do in the circumstances.
I'd welcome the views of others on the above

HI,
thank you very much for your valuable reply,
i have one more question.
Can you clarify me ,if i will do
calculation in UK-mainline practice
placing of singal -indian railways practice
is it acceptable one.
