The size of a program is N.And the memory occupied by the program is given by M=square root of 100N.If the size of the program is increased by 1% then how much memory now occupied?

Ans : 0.5%

pls tell me the way how u solved this

thanks

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.
        s,  dM/M=.5%.......................Answer
 

Answer is 0.5% bcoz...


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.
