14. Assume that new tax rates and deduction rules have been implemented as shown below:
Annual income (in `) Tax Rates for Females Tax Rates for Males
up to 100000 nil nil
100000 to 200000 10% 12%
200000 to 300000 20% 22%
300000 to 500000 30% 33%

20. Write a program to input a number and print all the prime perfect number upto n. (Prime perfect number are those numbers
whose all the factors are prime)
E.g., 6 = 1 + 2 + 3
21. A school is allocates grade and remarks on the basis of total marks (total of 3 subject of 100 marks) obtained by the student as
per the following criteria:
Marks obtain Grade allocated Remark on grades
