Answer:
HERE IS YOUR ANSWER ( -_- )
Step-by-step explanation:
Total expenditure for the year
= [2200×3+2250×4+3120×5][2200×3+2250×4+3120×5]
= 6600 + 9000 + 15600
= Rs.31200
Total savings = Rs.1260
Total income = expenses + savings = 31200 +1260 = Rs.32460
Therefore, Average income = 32460123246012 = Rs.2705
