Given an integer U denoting the amount of KWh units of electricity consumed, the task is to calculate the electricity bill with the help of the below charges:
- 1 to 100 units –
- 100 to 200 units –
- 200 to 300 units –
- above 300 units –
Examples:
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 = 3500Input: 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:
- Check units consumed is less than equal to the 100, If yes then the total electricity bill will be:
- Else if, check that units consumed is less than equal to the 200, if yes then total electricity bill will be:
- Else if, check that units consumed is less than equal to the 300, if yes then total electricity bill will be:
- Else if, check that units consumed greater than 300, if yes then total electricity bill will be:
Below is the implementation of the above approach:
