The average monthly expenditure of a family for the first four months is ₹13,750, for the next three months is ₹11,750 and for the last five months is ₹31,750. If the family saves ₹15,550 during the whole year, find the average monthly income of the family during the year. (Consider integral part only)
Answer & explanation
Correct answer: option 2
Sum of expenditure = 4 ×13750 + 3 ×11750 + 5 ×31750 = 55000 + 35250 + 158750 = 249000
Total income = 249000 + 15550 = 264550
= 22045 (approx)
