PLEASE CHANGE THE OA!
OA of this question is B. Here's how:

Average Speed = Total Distance/Total Time
36 = (Distance of First part + Distance of Second part)/(Time for first part + time for second)
36 = (30t1 + 40t2)/(t1 + t2)
36(t1 + t2) = 30t1 + 40t2
36t1 + 36t2 = 30t1 + 40t2
6t1 = 4t2
t2 = 1.5 t1

Which means, t2 is greater than t1.

As both Speed and Time of second part is greater than that of first part of the trip, thus, QUANTITY B IS GREATER

As the average is near to 40, so we can say B is greater.
