A) 29/5 B) 37/4
C) 42 D) 54

Answer:   C) 42

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)

{\color{Blue} \therefore } 125 : 150 :: 35 : x    {\color{Blue} \Rightarrow }    125 x x = 150 x 35

 {\color{Blue} \Rightarrow x=\frac{150\times 35}{125}}

{\color{Blue} \Rightarrow } x = 42.
