Cost of the first min = 0.75

Additional charge for each min = 0.25.

Total cost = 5.75.

5.75 - 0.75 = 5.00.

5.00 is the total cost of 0.25 slot. dividing 5 by 0.25 we can find out additional mins .

5 / 0.25 = 20.

Total duration : 20 + 1 = 21.

bro, we are asked to determine the duration of the call. 1 must be added to 20 .
