There is a gap of three persons between G and R. C is staying on the topmost floor. Neither P nor M is staying on the floor 5. Q is staying middle of P and M. R is staying on the floor 1. M is not an immediate neighbour of G.

Immediate neighbours of the person who is staying in floor 3?

Select the odd group of numbers. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g.13 – Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)
