(d) 108​

Answer 1

Answer:

sorry buddy I'm busy

Answer 2

Answer:

96

Step-by-step explanation:

Formula used here is  a [b] c =>  [ (a x b) + (c x a) ] (c-b)

So for  2 [3] 4 = [ (2 x 3) + (4 x 2) ] (4 -3) = [ 6 + 8] 2 = 14 x 1 = 14

           3 [4] 6 = [ ( 3 x 4) + (6 x 3)] (6-4) = [12 + 18] 2 = 30 x 2 = 60

           4 [5] 7 = [ (4 x 5) + (7 x 4)]) (7-5) = [20 + 28] 2 = 48 x 2 = 96

Hence answer is 96.
