Solve que 79 as fast as possible.

​Q79. If A = 2 tan–1 2 2 - 1 and   B   =   3   sin 1 1 3 +   sin 1 3 5 ,   then
        (A) B < A <  7 π 12                     (B)  7 π 12 < B < A               (C) B <  7 π 12 < A           (D) 7 π 12 < A < B
           

i would advice you to put the respective values of the inverse trignometric functions and then compute the ans.
sin-13/5 = 370 
sin-11/3=150
tan-1(23/2-1)= 620
then option c is correct
even such kind of questions are most probably meant for the competitives only.
