To solve the question `32% of 420 + 36% of 540`, we can break it down step by step.

### Step 1: Calculate 32% of 420
To find 32% of 420, we can use the formula:
\[ \text{Percentage} = \frac{\text{Percentage Value}}{100} \times \text{Total Value} \]
So, we calculate:
\[ 32\% \text{ of } 420 = \frac{32}{100} \times 420 \]

### Step 2: Simplify the calculation
Now, we simplify:
\[ = \frac{32 \times 420}{100} \]
\[ = \frac{13440}{100} \]
\[ = 134.4 \]

### Step 3: Calculate 36% of 540
Next, we calculate 36% of 540 using the same formula:
\[ 36\% \text{ of } 540 = \frac{36}{100} \times 540 \]

### Step 4: Simplify this calculation
Now, we simplify:
\[ = \frac{36 \times 540}{100} \]
\[ = \frac{19440}{100} \]
\[ = 194.4 \]

### Step 5: Add the two results together
Now we add the results from Step 2 and Step 4:
\[ 32\% \text{ of } 420 + 36\% \text{ of } 540 = 134.4 + 194.4 \]

### Step 6: Final calculation
Now we perform the addition:
\[ = 328.8 \]
