    Answer:  (1) 4%

    Explanation:-
    The amount in 2 years = Rs. 16, 900
    And, the amount in 3 years = Rs. 17, 576

    Compound Interest in a year = 17, 576 – 16, 900
     =Rs. 676

    Then,  676 = 16, 900 x R/100
     676 = 169 R
    R = 676/169
    X = 4 % 

    Then, the rate of interest per annum is 4 %. 

    Hence, the correct answer is option (1) 4%.
