Explanation

Saurabh's work rate: 1/36 per day. Tarun's work rate: 1/48 per day. Combined (Saurabh + Tarun + Pawan) rate: 1/12 per day. Pawan's rate = 1/12 - (1/36 + 1/48) = 1/12 - 7/144 = 12/144 - 7/144 = 5/144. Ratio of work rates: Saurabh : Tarun : Pawan = 4/144 : 3/144 : 5/144 = 4:3:5. Total parts = 12, Pawan's share = 5/12 of ₹28,800 = ₹12,000.
