I. 

Circumference of the floor is 44 feet.

 II. 

The height of the wall of the room is 12 feet.

I alone sufficient while II alone not sufficient to answer
II alone sufficient while I alone not sufficient to answer
Either I or II alone sufficient to answer
Both I and II are not sufficient to answer
Both I and II are necessary to answer
Answer: Option
Explanation:

I gives, 2R = 44.

II gives, H = 12.

A = 2RH = (44 x 12).

Cost of painting = Rs. (44 x 12 x 20).

Thus, I and II together give the answer.

The question is really tricky. They have given circumference, not perimeter which means the room is cylindrical. Am I right? Explain please.

@Bikash.

Instead of perimeter circumference word is used that's why it is cylindrical.

It's nowhere mentioned in the question that the room is cylindrical. Then how it will? Please explain.

@All.

They have given the circumference in the question not the perimeter. Hence the room is circular in shape.

Yes, in a Question it is not mentioned that room is cylindrical but in option, they gave data in terms of a circle. Due to this, we have to assume wall as a cylindrical in shape.

Cylindrical room? The answer cannot be determined by the data.
Rijul said:   8 years ago
How can we take it as cylindrical?
Kritika said:   9 years ago
The shape of the room is not mentioned. Then, how can we consider it as cylindrical?
Ashish Kumar said:   1 decade ago
It is not mentioned that the room is cylindrical. Normally one assumes the room is rectangular in shape.
