Program to calculate gross salary of a person
  • Last Updated : 16 Sep, 2020

Given an integer basic and a character grade which denotes the basic salary and grade of a person respectively, the task is to find the gross salary of the person.

Gross Salary: The final salary computed after the additions of DA, HRA and other allowances. The formula for Gross Salary is defined as below:

Gross Salary = Basic + HRA + DA + Allow – PF
Here, HRA = 20% of Basic 
DA = 50% of basic 
Allow = 1700 if grade = ‘A’ 
Allow = 1500 if grade = ‘B’ 
Allow = 1300 if grade = ‘C’ 
PF = 11% of basic

Examples:

Input: basic = 10000, grade = ‘A’
Output: 17600



Input: basic = 4567, grade = ‘B’
Output: 8762

Approach: The idea is to find the allowance on the basis of the grade and then compute the HRA, DA, and PF on the basis of the basic salary. Below is the illustration of the computation of HRA, DA, and PF:

  • HRA: House Rent Allowance is 20% of the basic salary:

    HRA = Basic Salary * 0.20

  • DA: Daily Allowance is the 50% of the basic salary:

    DA = Basic Salary * 0.5

  • PF: Provident Fund is the 11% of the basic salary.

    PF = Basic Salary * 0.11

Below is the implementation of the above approach:
