Solution

Total weight of two varieties of rice = 15 + 25 = 40 kg

Total cost price of 40 kg of rice $= (15 \times 29) + (25 \times 20)$
$= ₹ (435 + 500)$
$= ₹ 935$

Selling price of 1 kg of mixed rice = ₹27

The total SP of 40 kgs of mixed rice $= 40 \times 27 = ₹ 1080$

Profit = Selling price - cost price

= 1080−935

= ₹145
