Answer 1

B.  It will take 24 minutes less.

Explanation:

Given : Mineral water factory has 6 machines that package 3000 bottles in 1 hour.

There is an inverse relation between the number of machines and the time taken to do the work.

Equation of inverse variation: $x_1y_1=x_2y_2$

If  4 more machines of the same type are also put into use, the total machines now = 6+4=10

Put  $x_1=6,\ y_1=1$ and $x_2=10$  in the above equation , we get

$6\times1=10\times y_2\\\\ y_2=\dfrac{6}{10}=0.6$

Time taken by 10 machines = 0.6 hour = $0.6\times60=36\text{ minutes}$  [1 hour = 60 minutes]

Time difference = 60 minutes - 36 minutes = 24 minutes.

So , it will take 24 minutes less.
