Dear shefali

1600=2752

 

so number of all divisors =(7+1)(2+1) =21

 but these diviser also include    1,50,52 ie  1,5,25

  which is not even 

so even divisior =21-3 =18

I think the process mentioned above is correct, but the calculation is not clear  That is,
      1600=2^6 × 5^2           (not 2 raised by 7)
Number of divisors=(6+1)(2+1)=21
And finally minus 3 as explained above.
So, the final answer is 21-3=18
 
Thanks  for considering my view. 
Regards.
