#### Question

Find the correct answer from the alternatives given.

The formula to find mean from a grouped frequency table is \[X = A + \frac{\sum f_i u_i}{\sum f_i} \times hg\] .

##### Options

\[\frac{x_i + A}{g}\]

\[\left( x_i - A \right)\]

\[\frac{x_i - A}{g}\]

- \[\frac{A - x_i}{g}\]

#### Solution

To find mean of a grouped frequency table using

\[X = A + \frac{\sum f_i u_i}{\sum f_i} \times hg\]

In this formula, \[u_i = \frac{x_i - A}{g}\]

In this formula, \[u_i = \frac{x_i - A}{g}\]

Is there an error in this question or solution?
