Answer:
sorry I don't know the answer
When Kirti rented a scooty for 330 minutes, she paid Rs 56 for it.
Time for which the scooty is rented by Kirti = 330 minutes = (330/60) = 5.5 hours. [As 1 minute = 1/60 hours]
For the first hour charges = Rs 8.75
So, number of hours more the scooty was rented = (5.5-1) = 4.5 hours.
Now, these remaining hours are charged at Rs 5.25 per hour.
So, charges for 4.5 hours = Rs ( 5.25 × 4.5) = Rs 23.625
Thus total charges = Charges for the 1st hour + Charges for the remaining hours = Rs (8.75 + 23.625) = Rs 32.375
[In the question, Rs 5.25 should be the charge for half hourly basis instead of hourly, after the 1st hour]
So, if Rs 5.25 is charged for half an hour, then charge for an hour is Rs (5.25×2) = Rs 10.5
So, charges for 4.5 hours = Rs ( 10.5 × 4.5) = Rs 47.25
Thus total charges = Charges for the 1st hour + Charges for the remaining hours = Rs (8.75 + 47.25) = Rs 56.00
Total charge is Rs 56.
