Option B. (numbers)

By the information given:

It is also given that Equations is performed before Functions; except in Chennai.

Let us consider these 2 cases:

Case (i):

One of the days Functions must be taught first. On that day whatever the position of Equations is, it must be after Functions.

So the following cases are possible:

Case (ii):

On one day Equations must be taught first. On that day whatever the position of Functions be, it must be after Equations.

It is seen that this is happening only in Chennai and that Equations will be 1 and Functions will be 5 (that is the only possibility considering case (i))

Also,

In Kolkata as 1, 2, 3 is already occupied Functions 4 and Equations 5 can be the only possibility.

Functions 3, Equations 4 can be taken only by Mumbai (as 3 and 4 r already filled inDelhinHyderabad)

Hyderabadcan’t take Functions 2, Equations 3 as h already has 3, and henceHyderabadhas to take Equations 1, Functions 2.

NowDelhihas to take Equations 2, Functions 3

Now the table looks like this:

Now, fill in the table with other values:
