Answer: Option
Explanation:
After 10 days : 150 men had food for 35 days.
Suppose 125 men had food for x days.
Now, Less men, More days (Indirect Proportion)
125 : 150 :: 35 : x 
125 x x = 150 x 35
 x = |
150 x 35 |
| 125 |
x = 42.

Let the required number of days be 'x'.
150*45=(150*10)+(125*x),
Hence, x=42.
150*45=(150*10)+(125*x),
Hence, x=42.

@Pushpak.
I guess 1430 men came after 17 days,
2200*33 = (2200+x) * 20.

Why can't the equation be 125 * 150 = 45 * x?

(150*45) = (10*150)+(125*y).
So y = 42.
So y = 42.
