Question

in a mall car parking charges are 10 rupees for the first hour and 5 rupees for every extra half an hour or part thereof. how much is the parking fee for 2 upon 3 by 4 hours.​

Answer 1

Answer:

Cost of first hour  = Rs 10 (Given)

Find the duration remaining after deducting the first hour:

2 3/4 hour - 1 hour = 1 3/4 hours

Find the number of half hours to be paid:

1 3/4 hours = 1/2 hour + 1/2 hour + 1/2 hour + 1/4 hour

Since it is half hour or part there of,

total number of  1/2 hours payable = 4

Amount needed to be paid for the half hours duration:

4 x 5 = Rs 20

Find the total charge:

Total charge = 10 + 20 = Rs 30

Answer: The parking fee is Rs 30.
