COUD U PLEASE EXPLN
WHY THEY R IN PARALLEL

it is parallel between across the middle resistor

across the two ends it is

Use Geometrical symmetry or kirchoff's law to do these problems

I CAN SOLVE IT USING KIRCHOFFS LAW BUT IT IS 2 LENGTHY

Sorry for my earlier reply it is indeed a parallel connection
See the image

HOW CAN U REPLACE THE DIAGRAMS

I haven't replaced the diagrams just rearranged the geometry without changing any connections.

Check HCVERMA electric current problem 30 its the same problem
you can move around the resistors physically without changing the arrangement

Hi! Notice that the wire connecting the leftmost plate of the leftmost capacitor also connects the rightmost plate of the middle one. See , they are in parallel. Now can go for the same logic with the third one and see yourself.
 
Also make use of the fact that P.D. between the two capacitors is the same (Similarly for the third);

mark the two end terminals as A and B. Check the plates of each capacitor and you will find that if one plate is connected to A the other will be connected to B. It implies that all the capcitors share the same potential difference and hence they are parallel
