  1. The average expenditure of a man for the first five month is Rs. 120 and for the next seven months it is Rs . 130. if he saves Rs 299 in that year, his monthly average income is ?
    1. Rs. 140
    2. Rs. 150
    3. Rs. 160
    4. Rs. 170
  1. Correct Option: B

    Total income = total expenditure + total saving
    = Rs. (120 X 5 + 130 X 7 + 290)
    =Rs. 1800

    Average monthly income
    =1800 / 12
    =150 Rs.
