Pf Calculation - Basic Salary 8000 And Da 2000 Hra 2000

Dear sir or mam,
if a person having basic salary 8000 and da 2000 hra 2000 working days 20 in the month of september than gross salary would be 9333 than what would be the pf amount and on which it would calculate pls slove this and show the example by solving this.

10000*80/100 = 8000 basic 12 % 960
9333*80/100 = 7466 basic 12% 896

Dear SK 4882937,
PF is deductible on earned Basic & DA. If an employee is drawing Basic Rs.8,000 and DA Rs.2,000 per month then 20 days salary for September would be 8000+2000=10000*20/30=6,667 (Earned Basic & DA).
Thus the PF contribution will be on Rs.6667*12/100=Rs.800.
