Answer: Option D

Solution(By Examveda Team)

According to the question,
Cost price of mixture of rice
= 15 × 29 + 25 × 20
= 435 + 500
= Rs. 935
Selling price of 1 kg mixture of rice = Rs. 27
Selling price of 40 kg mixture of rice
= 27 × 40 = Rs. 1080.
Profit = Selling price - Cost price
= 1080 - 935
= Rs. 145
