Answer 2

Problem Analysis

To solve this problem, we need to calculate the remaining amount of grain to sell. We know that 5 bags of rice, each weighing 40 kg, were delivered, and 5 bags of wheat, each weighing 35 kg, were also delivered. On the first day, 120 kg of rice and 140 kg of wheat were sold. We need to find out how much grain is left to sell.

Solution

To find the remaining amount of grain to sell, we need to subtract the amount sold from the total amount delivered.

Let's calculate the remaining amount of rice and wheat separately.

# Rice:

- Total amount of rice delivered: 5 bags * 40 kg/bag = 200 kg. - Amount of rice sold: 120 kg. - Remaining amount of rice to sell: Total amount of rice delivered - Amount of rice sold.

# Wheat:

- Total amount of wheat delivered: 5 bags * 35 kg/bag = 175 kg. - Amount of wheat sold: 140 kg. - Remaining amount of wheat to sell: Total amount of wheat delivered - Amount of wheat sold.

Now, let's calculate the remaining amount of grain to sell by adding the remaining amount of rice and wheat.

Calculation

- Remaining amount of rice to sell: 200 kg - 120 kg = 80 kg. - Remaining amount of wheat to sell: 175 kg - 140 kg = 35 kg. - Remaining amount of grain to sell: Remaining amount of rice to sell + Remaining amount of wheat to sell.

Answer

The remaining amount of grain to sell is 115 kg.

Conclusion

After selling 120 kg of rice and 140 kg of wheat, there are 115 kg of grain left to sell.
