From 1, we find that 

Total money with Naresh and Ajay = Rs {(28/1OO)x 75000} = 21000. 

From II, we find that money with Ajay = Rs {(3/4) x 21000 } = 15750.

So, both I and II are required. 

From I, we have : M>V, V> S, V > N.

From II. we have : Mukul is the oldest.

From 111, we have : S > N Combining (I) and (III) we get : M> V, V >S>N or M > V> S > N.
