    Answer is Rs.7,000.

    Explanation:-
    Let the sum deposit at the bank be Rs. X 

    According to the question, 
    X x 5/100 – X 3.5/100 = 105
    (5 X – 3.5 X)/100 = 105
    1.5 X = 105 x 100
    15 X = 105 x 1000
    X = 7 x 1000
    X = 7, 000

    Then, the sum deposited at the bank was Rs. 7, 000. 

    Hence, the correct answer is option (3) Rs. 7, 000.
