    Answer: Option a
    Explanation:
    Let the cost of a chair and that of a table be Rs. x and Rs. y respectively.
    Then, 10x = 4y or y=5x/2
    15x + 2y = 4000
    15x+2(5x/2)=4000
    X=200
    Then y=500
    Hence, the cost of 12 chairs and 3 tables = 12x + 3y
    = Rs. (2400 + 1500)
    = Rs. 3900.
