(A)We try to check for all solutions other than (2013,1)& (2013,2012)
2013 = 3*11*61
Therefore n≥61.(otherwise it can never have the prime factor 61)
We can check that r =0,(61-0),1,(61-1),2,(61-2) does not satisfy the given condition.
For 58≥r≥3.
\inline \dpi{200} \binom{n}{r}\geq \binom{n}{3}\geq \binom{61}{3}> 2013
Hence no other solution can exist.
(B)Similarly for 2014 solutions other than (2014,1)& (2014,2013) does not exist.
