Let the number of Soldiers in Battalion be N
Earlier, each Soldier will give Rs. N
Earlier total collection was
(Number of Soldiers) x (each's contribution) (N) x (N) = N²
Now, one Soldier's contribution is increased by 50,  So, total collection now = N x N + 50= 251051 N² + 50= 251051 
N² = 251051 – 50 
N² = 251001 
So, N2 = 501², N = 501 or -501 But number of Soldiers can’t be negative, so N = 501 Therefore, number of Soldiers = 501
