1.1 Converting Input Strings
Write a program to convert strings to an integer and float and display its type.
Sample Output:
10,<class 'int'>
10.9,<class 'float'>

For example:
Input	Result
10
10.9	10,<class 'int'>
10.9,<class 'float'>




a=input()
b=input()
c=int(a)
d=float(b)
print(c,type(c),sep=",")
print("{:0.1f}".format(d),type(d),sep=",")

 


1.2 Gross Salary
Ramesh’s basic salary is input through the keyboard. His dearness allowance is 40% of his basic salary, and his house rent allowance is 20% of his basic salary. Write a program to calculate his gross salary.

Sample Input:
10000
Sample Output:
16000
For example:
Input	Result
10000	16000



s=int(input())
da=s*0.4
ha=s*0.2
print(int(s+da+ha))


 

1.3 Square Root
Write a simple python program to find the square root of a given floating point number. The output should be displayed with 3 decimal places.


Sample Input:
8.00
Sample Output:
2.828
For example:
Input	Result
14.00	3.742

import math
a=float(input())
s=math.sqrt(a)
print("{:.3f}".format(s))

 

1.4 Gain percent
Alfred buys an old scooter for Rs. X and spends Rs. Y on its repairs. If he sells the scooter for Rs. Z (Z>X+Y). Write a program to help Alfred to find his gain percent. Get all the above-mentioned values through the keyboard and find the gain percent.

Input Format:
The first line contains the Rs X
The second line contains Rs Y
The third line contains Rs Z
Sample Input:
10000
250
15000
Sample Output:
46.34 is the gain percent.

For example:
Input	Result
45500
500
60000	30.43 is the gain percent.

buys=int(input())
repair=int(input())
sells=int(input())
g=(((sells-(buys+repair))/(buys+repair))*100)
print("{:.2f}".format(g), "is the gain percent.")

 



1.5 Deposits
In many jurisdictions, a small deposit is added to drink containers to encourage people to recycle them. In one particular jurisdiction, drink containers holding one liter or less have a $0.10 deposit and drink containers holding more than one liter have a $0.25 deposit. Write a program that reads the number of containers of each size(less and more)  from the user. Your program should continue by computing and displaying the refund that will be received for returning those containers. Format the output so that it includes a dollar sign and always displays exactly two decimal places.
Sample Input
10
20
Sample Output
Your total refund will be $6.00.

For example:
Input	Result
20
20	Your total refund will be $7.00.



a=int(input())
b=int(input())
c=a*0.1
d=b*0.25
e=c+d
print("Your total refund will be ${:.2f}.".format(e))

 




1.6 Carpenter
Justin is a carpenter who works on an hourly basis. He works in a company where he is paid Rs 50 for an hour on weekdays and Rs 80 for an hour on weekends. He works 10 hrs more on weekdays than weekends. If the salary paid for him is given, write a program to find the number of hours he has worked on weekdays and weekends.
Hint:
If the final result(hrs) are in -ve convert that to +ve using abs() function
The abs() function returns the absolute value of the given number.

number = -20
absolute_number = abs(number)
print(absolute_number)
# Output:20

 Sample Input:
450
Sample Output:
weekdays 10.38
weekend 0.38

For example:
Input	Result
450	weekdays 10.38
weekend 0.38




	s=int(input())
	a=(500-s)/130
	print("weekdays {:.2f}".format(abs(a)+10))
	print("weekend {:.2f}".format(abs(a)))
