Question

The mess charges for $35$ students for $24$ days is Rs. $6300$. In how many days will the mess charges be Rs. $3375$ for $25$ students?

• A. $18$ days
• B. $15$ days
• C. $12$ days
• D. $9$ days

Answer 1

The correct option is A $18$ days

Let us calculate $mess$ $charge$ per person per day

$=\frac{6300}{35\times 24}=7.5$

Now,

$\frac{3375}{25\times days}=7.5$

$\Rightarrow 3375=Days\times 25\times 7.5$

$\Rightarrow Days=18$

Therefore, Answer is $\left(A\right)$
