To find out how much more the amount paid on phone bills by family 'Y' is compared to their electricity bills, we first need to calculate the total amount paid on each type over the given months.

1. First, extract the monthly phone and electricity bills for family 'Y' from the table:

1. Calculate the total amount spent on phone bills:

Total Phone Bills (Family Y) = 1000 + 1200 + 1250 + 1600 + 1100 = ₹6150

1. Calculate the total amount spent on electricity bills. Note: Substitute any missing data with 0 if necessary.

Total Electricity Bills (Family Y) = 0 + 1600 + 400 + 500 + 1500 = ₹4000

1. Calculate the percentage increase of phone bills over electricity bills:

Formula: \(\text{Percentage Increase} = \left(\frac{\text{Phone Bills} - \text{Electricity Bills}}{\text{Electricity Bills}}\right) \times 100\)

\(\text{Percentage Increase} = \left(\frac{6150 - 4000}{4000}\right) \times 100 = \frac{2150}{4000} \times 100 = 53.75\%\)

1. The question asks by approximately what percentage it is more. The option closest to the calculated value (53.75%) is 12%. However, there seems to be an error in the relationship described in the problem, since 12% does not match our calculation. It's possible the question is intended to test an adjacent concept and options are incorrect in context.

Therefore, based on our calculated value, 53.75% is correct given our assumptions of data substitution and logical calculation. Verify with any supervisory guidance or corrections regarding the context or data misinterpretations.
