Ravi earned a sum of Rs. 10800 and donated `40%` of it to charity. He give `15%` of the remaining amount to Ramu. After giving `25%` of the remaining amount to Anitha, he deposited the rest in a bank. How much money did he deposit in the bank?

Answer

To solve the problem step by step, we will follow the sequence of actions performed by Ravi with his earnings.

### Step 1: Calculate the amount donated to charity.
Ravi earned a total of Rs. 10,800 and donated 40% of it to charity.

\[ \text{Amount donated to charity} = 40\% \text{ of } 10,800 = \frac{40}{100} \times 10,800 = 4,320 \]

### Step 2: Calculate the remaining amount after the charity donation.
Now, we subtract the amount donated to charity from the total earnings to find out how much money Ravi has left.

\[ \text{Remaining amount} = 10,800 - 4,320 = 6,480 \]

### Step 3: Calculate the amount given to Ramu.
Ravi then gave 15% of the remaining amount to Ramu.

\[ \text{Amount given to Ramu} = 15\% \text{ of } 6,480 = \frac{15}{100} \times 6,480 = 972 \]

### Step 4: Calculate the remaining amount after giving to Ramu.
Next, we subtract the amount given to Ramu from the remaining amount.

\[ \text{Remaining amount after Ramu} = 6,480 - 972 = 5,508 \]

### Step 5: Calculate the amount given to Anitha.
Ravi then gave 25% of the remaining amount to Anitha.

\[ \text{Amount given to Anitha} = 25\% \text{ of } 5,508 = \frac{25}{100} \times 5,508 = 1,377 \]

### Step 6: Calculate the remaining amount after giving to Anitha.
We subtract the amount given to Anitha from the remaining amount.

\[ \text{Remaining amount after Anitha} = 5,508 - 1,377 = 4,131 \]

### Step 7: Determine the amount deposited in the bank.
The final amount that Ravi deposited in the bank is the remaining amount after all donations.

\[ \text{Amount deposited in bank} = 4,131 \]

Thus, the amount Ravi deposited in the bank is **Rs. 4,131**.
