Gross salary may include:
• Basic salary
• House Rent
• Conveyance allowance
• Utilities allowance

So, farri you can calculate by yourself. 

Gross Salary = basic salary + house rent + utility allowance

                 = 10000 + 4500  + 1000

                 = 15500

and medical and social charges are calculated o the basis of gross salary ... ok thanku :)

**Friends*** MTH-302 New Video lectures by Ahmad Siddiqui needed ,,, somebody please give me any source from where i can download or watch these new lectures... i searched them on youtube few are available but most of them are missing... i need new videos please somebody update.



Basic Salary = 10,000
 House rent 45%
= 10,000 * 45%
= 4,500 Rs.
 Utilities 10%
= 10,000 * 10%
= 1,000 Rs.
Gross Salary = basic salary + house Rent + Utilities Allowance
= 10,000 + 4,500 + 1,000
= 15,500 Rs.
 Medical Allowance 5%
Medical allowance and social charges are calculated on gross salary.
= 15,500 * 5%
= 775 Rs
 Social Charges 9%
= 15,500 * 9%
= 1395 Rs.
