STEP 1: Calculate Cost Price :

Cost Price of 200 kg = 25 × 200 = 5000 rupees.

............................................................................................................

STEP 2: Calculate Expected Earning :

Gain = 8% × 5000 = 0.08 × 5000 = 400 rupees

Expected Earning = 5000 + 400 = 5400 rupees

............................................................................................................

STEP 3: Find earnings from the sales of 80kg at 10% gain :

Cost of 80kg = 25 × 80 = 2000 rupees

Gain = 10% of 2000 = 0.1 × 2000 = 200 rupees

Total earnings = 2000 + 200 = 2200 rupees

............................................................................................................

STEP 4: Find earnings from the sales of 40kg at 4% loss :

Cost of 40 kg = 25 × 40 = 1000 rupees

Loss = 40% × 1000 = 0.04 × 1000 = 40 rupees

Total Earnings = 1000 - 40 = 960 rupees

............................................................................................................

STEP 5: Find remaining rice to sell :

Remaining = 200 - 80 - 40 = 80 kg

............................................................................................................

STEP 6: Find the remaining of the expected earning

5400 - 2200 - 960 = 2240 rupees

............................................................................................................

STEP 7: Find the rate pr kg :

80 kg = 2240 rupees

1 kg = 2240 ÷ 80 = 28 rupees

............................................................................................................

Answer: He needs to sell the remaining rice at 28 rupees per kg.
