    In a camp, 95 men had provisions for 200 days. After 5 days, 30 men left the camp. For how many days will the remaining provisions last?

    A)  \[180\]                

    B)         \[285\]                

    C)  \[139\frac{16}{19}\]                      

    D)         \[200\]

    Correct Answer: B

    Solution :

    Let the remaining food last for x days. 95 men had provisions for 195 days. 65 men had provisions for x days. Less men \[\Rightarrow \]more days. \[\therefore \]  \[65:95:\,\,:95:x\] \[\Rightarrow \]               \[(65\times x)=(95\times 195)\] \[\Rightarrow \]               \[x=\frac{95\times 195}{65}=285\]
