The frequency of tuning fork 'A' is `2 5 0Hz`. It produces `6` beats/sec, when sounded together with another tunning fork B. If its arms are loaded with wax then it produces `4` beats/sec. Find the frequency of tuning fork `B`.

Explanation

To find the frequency of tuning fork B, we can follow these steps:

### Step 1: Understand the Beat Frequency
When two tuning forks are sounded together, the beat frequency is the absolute difference between their frequencies. The formula for beat frequency is given by:
\[ \text{Beat Frequency} = |f_1 - f_2| \]
where \( f_1 \) is the frequency of tuning fork A and \( f_2 \) is the frequency of tuning fork B.

### Step 2: Set Up the Known Frequencies
