3300 men -> 32 days -> 850 g/head
After 7 days,
3300 men -> 25 days -> 850 g/head
After reinforcement = 'x' arrives,
(3300+x) men -> 17 days -> 825 g/head

Now, men count is inversely proportional to the days for survival
So,
3300*850 -> 1/25
(3300+x)*825 -> 1/17
Solving the above two we get,
3300 + x = (3300*850*25)/(17*825)
So, x = 5000-3300 = 1700
