given..        M=10N^(1/2)................................eqn (1)
dM/dN=10.1/2.N^(-1/2)
or,  dM=1/2(10.N^1/2)dN/N
dM=1/2(M)dN/N........................frm eqn (1)
dM/M=1/2.dN/N
put dN/N=1%.........................................frm d qs.

take n=100thenmemory m=sqrt(100n)=sqrt(10000)=100

Increase n by 1% then

n=101then memory m=sqrt(100n)=sqrt(10100)=100.5

then memory will be increased by 0.5%

i think there is no need to increase the memory though the size is increasd.
