Program 1
Write a program by using class „Employee‟ to accept Basic Pay of an employee. Calculate the
allowance/deductions as given below.
Finally, find and display the Gross and Net pay.
Allowance / Deduction Rate:
Dearness Allowance (DA) : 30% of Basic Pay
House Rent Allowance (HRA): 15 % of Basic Pay
Provident Fund (PF) : 12.5% of Basic Pay
Gross Pay = Basic Pay + Dearness Allowance + House Rent Allowance
Net Pay = Gross Pay – Provident Fund

Given below is a hypothetical table showing the rage of income tax for the Indian citizen, who is up
to the age of 60 years.
Taxable Income (TI) in ₹ Income Tax in ₹
Up to ₹ 2,50,000/- Nil
More than ₹ 2,50,000 and less than or equal to ₹ 5,00,000 (TI – 1,60,000) * 10%
More than ₹ 5,00,000 and less than or equal to ₹ 10,00,000 (TI – 5,00,000) * 20% + ₹ 34,000
More than ₹ 10,00,000 (TI – 10,00,000) * 30% + ₹ 94,000
Write a program to input the name, age and taxable income of a person. If the age is more than 60
years then display the message “Wrong Category”. If the age is less than or equal to 60 years then

Program 7
Write a program to enter a number and check whether the numbers is Keith number or Not.
(An n digit number x is called Keith number if it appears in a Fibonacci sequence generated
using its digits. The sequence has first n terms as digits of x and other terms are recursively
evaluated as sum of previous n terms.)
Example: 197 is a Keith Number
Explanation: 197 has 3 digits, so n = 3
First 3 terms as 1, 9, 7 and remaining terms evaluated
using sum of previous 1, 9, 7, 17, 33, 57, 107, 197, ...

Program 9
Write a program to accept a word and check whether the word is Happy word or not.
(A 'Happy Word' is defined as - Calculate the word's value based on position of the letters in
English alphabet. On the basis of word's value, find the sum of the squares of its digits. Repeat the
process with the resultant number until the number equals 1 (one). If the number ends with 1 then
the word is called a 'Happy word'.)
Sample Input : VAT
[Place value of V=22,A=1,T=20 (Hint: A=1, B=2 ..., Z=26) Solution: 22120 -> 22 + 22 + 12 + 02 =
13 -> 12 + 32=10 -> 12 + 02 = 1]
Sample Output : Happy word
