Bill amount probably consisting of labour, Food & Shelter, profit etc. Total PF deduction is 29,604/- which is supposed to be 25% of labour cost ( Employer-12%+Employee-12%+ Admin etc-1%. charges). Therefore total labour cost is 29,604 x 4 = 1,18,416/-. The labour cost is again 36% of total bill amount which is common for construction work.
Hope this will satisfy your query.
