    Answer:  (3) 1920
    Explanation:- 
    Given-
    Principal = Rs.2400, Time = 2.5 = 5/2 years  & Rate = 12 %
    Formula-
    Simple Interest  = P x R x T/100
    Where, P – principal , R – rate, T – time
    Then, Simple Interest = 2400 x 12 x 5/2 x 100
    = Rs.720
    Amount = Principal + Simple Interest
    Then,
    Amount = 2400 + 720
    = Rs.3120
    1200 + cow = 3120        (Given in question)
    Cow = 3120 – 1200
    Cow = Rs.1920
    Hence, the answer is (3) Rs.1920.
