Answer

To solve the problem of how many tigers remain in the wildlife sanctuary after a 15% increase, we can follow these steps:

### Step 1: Identify the initial number of tigers.
The initial number of tigers in the sanctuary last year is given as 720.

### Step 2: Calculate the increase in the number of tigers.
To find the increase, we need to calculate 15% of the initial number of tigers.

\[ \text{Increase} = \frac{15}{100} \times 720 \]

### Step 3: Perform the calculation for the increase.
Calculating the above expression:

\[ \text{Increase} = \frac{15 \times 720}{100} = \frac{10800}{100} = 108 \]

### Step 4: Add the increase to the initial number of tigers.
Now, we add the increase to the initial number of tigers to find the total number of tigers this year.

\[ \text{Total number of tigers this year} = 720 + 108 = 828 \]

### Final Answer:
The total number of tigers remaining in the wildlife sanctuary this year is **828**.
