Answer 1

Total Income = 46 * 70 * 4 * 90 pence = 11592 pounds.

Total expenditure = 1250 + (46 * 70 * 4 * 6 /100) + (250 * 12) + (125 * 52) = 11523 pounds.

Average excess of income per month = (Average income per month - Average expenditure per month)

= 11592/12 - 11523/12 = 5.75. So, nearest pound is 6.
