Given Information:
- 2X + 3Y - 7 = 0
- Mean of X = 1
- Mean deviation about mean of X = 0.3

Finding the Mean Deviation of Y about Mean:
- Since the mean of X is given as 1, we can find the value of X from the given equation.
- Substitute the value of X in the equation 2X + 3Y - 7 = 0 to find the value of Y.
- Once X and Y are calculated, find the mean deviation about mean of Y using the formula for mean deviation.

Calculating the Co-efficient of Mean Deviation of Y about Mean:
- The formula for the co-efficient of mean deviation is Mean Deviation / Mean.
- Find the mean deviation of Y about the mean of Y calculated in the previous step.
- Divide the mean deviation by the mean of Y to get the co-efficient of mean deviation of Y about mean.

Explanation:
- By solving the given equation and using the mean and mean deviation about mean of X, we can find the mean deviation of Y about mean and subsequently the co-efficient of mean deviation of Y about mean.
