Punit bought 385 bags of cement for some construction work. After the work was over, he returned 155 bags that were not used. If each bag of cement costs Rs. 315, find the amount of money Punit spent on cement.

Answer

To find the amount of money Punit spent on cement, we can follow these steps:

### Step 1: Determine the number of bags used
Punit bought a total of 385 bags of cement and returned 155 bags that were not used. To find the number of bags used, we subtract the number of bags returned from the total number of bags bought.

\[ \text{Number of bags used} = \text{Total bags bought} - \text{Bags returned} \]
\[ \text{Number of bags used} = 385 - 155 = 230 \]

### Step 2: Calculate the total cost of the used bags
Each bag of cement costs Rs. 315. Now, we need to calculate the total cost for the 230 bags that were used.

\[ \text{Total cost} = \text{Number of bags used} \times \text{Cost per bag} \]
\[ \text{Total cost} = 230 \times 315 \]

### Step 3: Perform the multiplication
Now, we will multiply 230 by 315 to find the total amount spent.

\[ 230 \times 315 = 72450 \]

### Final Answer
Thus, the amount of money Punit spent on cement is Rs. 72,450.
