Question

The minimum charge for first 180 telephone calls is Rs 200.If

the charge of each additional call is Rs 2, how much will be

charged for 210 telephone calls?​

Answer 1

Step-by-step explanation:

Input: U = 250

Output: 3500

Explanation:

Charge for the first 100 units – 10*100 = 1000

Charge for the 100 to 200 units – 15*100 = 1500

Charge for the 200 to 250 units – 20*50 = 1000

Total Electricity Bill = 1000 + 1500 + 1000 = 3500

Input: U = 95

Output: 950

Explanation:

Charge for the first 100 units – 10*95 = 950

Total Electricity Bill = 950

Approach: The idea is to identify the charge bar in which it falls and then calculate the bill according to the charges mentioned above. Below is the illustration of the steps:

Answer 2

Answer:

RS.260

Step-by-step explanation:

So the minimum charge for 180 calls is reached then RS.200 is obvious.

each additional call cost Rs.2.

210-180=30

30*2=60

so the total cost = Minimum call charge + additional call charge

                           = 200+60

                           =Rs.260
