    Answer: (B) 3, 000 

    Solution:-
    The average spend of an employee for first 8 months = Rs. 2, 500
    Therefore, he total spend in first 8 months = 2, 500 x 8
     = Rs. 20, 000

    And, the average spend for next 4 months = Rs. 1, 500
    Therefore, he total spend in next 4 months = 1, 500 x 4
     = Rs. 6, 000

    So, he total spend in a year = 20, 000 + 6, 000
     = Rs. 26, 000

    If he saves Rs. 10, 000 that year, 
    Then, the total earning in that year  = 26, 000 + 10, 000
     = Rs. 36, 000

    Thus, his monthly income = 36, 000/12
     = Rs. 3, 000

    Hence, the correct answer is option (B) 3, 000.
