Answer 1

Answer:

Step-by-step explanation:

students            days             Rs.

35                       24             6300

25                       18                 x

as student decrease , cost decreases . so it is direct variation

as days decreases, cost decreases , so it is direct variation

     x  =( 25/35 ) x (18/24) x 6300

       = 3375

Answer 2

Let us calculate mess charge per person per day

$= \frac{3600}{35 \times 24} = 7.5$

Now,

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

⇒3375=Days×25×7.5

⇒Days=18
