Hotel Bill

A Hotel is offering discounts to its customers.

Given charge per day

dayCharge based on category and numbers of days customer stayed days as inputs, write a JS arrow function to return the total bill with the discount.

Apply discounts on the following basis,

• 5%, if the customer stays more than 2 days
• 15%, if the customer stays more than 5 days

Input

• The first line of input contains a number dayCharge
• The second line of input contains a number days

 console.log(finalValue);

}

Final Value with Appreciation

Given principal amount

principal as an input, time period in years time and appreciation percentage apprPercentage as optional inputs, write a JS function to return the final value finalValue with the given appreciation percentage and time period. The default values for time and apprPercentage are 2 and 5 respectively.

Quick Tip

The formula to calculate the final value with appreciation is,

finalValue = principal * (1 + time * appreciation / 100)

Input

• The first line of input contains a number principal
• The second line (optional) of input contains a number time
• The third line (optional) of input contains a number apprPercentage

Output

• The output should be a single line containing the finalValue

Sample Input 2

3000

Sample Output 2

3300.0000000000005

Input

• The first line of input contains a string stringsArray
• The second line of input contains a string startString
• The third line of input contains a number endString
