    Answer : Option D

    Explanation :

    3.87 = 3+ (87/ 99) = 3+ (29/33) = 128/33............ (i)
    And, 2.59 = 2+ (59/99) = 257/ 99............. (ii)

    From equation (i) and (ii):

    (128/33) - (257/99)
    LCM of 33 and 99 is 99
    So, (3* 128 - 257)/ 99 = 1.282828...
    Hence, we can write it as 1.28
