1.     Given  below is a hypothetical table showing the rate of income tax for an Indian citizen, who is below or set up to 60 years.

 

Taxable Income(TI) in rupees	Income Tax in rupees
Above upto rupees 5 lacs	Nil
More than Rs 5,00,000 and less than or equal to 7,50,000	(TI-5,00,000)*10%
More than rupees 7,50,000 and less than or equal to rupees 10,00,000.	(TI-7,50,000)*20%+30,000
More than 10,00,000.	(TI-10,00,000)*30%+90,000

 

Write a python code to input the name age and taxable income of a person if the age is more than 60 years then display a message wrong category if the age is less than or equal to 60 years then compute and display the payable Income Tax along with the name of taxpayer pair as per the table given above.

Solution:

tax=0 name=input('Enter your name : ') age=int(input('Enter your age : ')) sal=int(input('Enter Salary : ')) if age>60:     print('Wrong Category') else:     if sal<=500000:         tax=0     if sal>500000 and sal<=750000:         tax=(sal-500000)*10/100     if sal>750000 and sal<=1000000:         tax=30000+(sal-750000)*20/100     if sal>1000000:         tax=90000+(sal-750000)*30/100 print('Name : ', name) print('Age : ',age) print('Tax Payable : ', tax)

 

2.     School displays a notice on the school notice board regarding admission in class 11th for choosing streams according to the marks obtained in English Maths and Science in class 10th Council examination.
