Question

first three hours charge rupees 6.50 additional rate per hour is rupees 2.5 if we used the TV for 20 hours find the amount to be paid in one month

Answer 1

Total cost of First 3 hrs = 6.5 * 3 = Rs 19.5

No. of Hours left = 20 - 3 = 17 hrs

Cost of rental after first 3 hrs = 6.5 + 2.5 = Rs 9

Therefore,

Cost of remaining 17 hrs = 17 * 9 = Rs 153

Amount to be paid in a day = 153 + 19.5 = Rs 172.5

Amount to be paid in a month = 172.5 * 30 = Rs 5175
