How to solve the problem?

Dear @Ankitha first consider a voltage V at point b/w R1 R2 R3 and then apply KCL at that point and then solve it for V. Again for voltage across R3 subtract VS2 from V.

Can anyone tell me how to do this problem?

By Kirchhoff's current law through nodal analysis.
Solution:
Consider the equation,
(VA-VS1/R1) + (VA/R2) + (VA-VS2/R3) = 0
Solution:
Consider the equation,
(VA-VS1/R1) + (VA/R2) + (VA-VS2/R3) = 0

Va = 4.18 then,
VR3 = 0.183v = 183mv.
VR3 = 0.183v = 183mv.

Super position theorem is very good one to solve this type of network. Because calculation gets very simple.

We consider the print between R1, R2 and R3 = VA.
VA-12/86+VA-0/37+VA-4/90 = 0.
(90*37)*VA-(90*37)*12+(86*90)*VA+(37*86)*VA-(37*86)*4/(37*90*86) = 0.
11966 VA-50024 = 0.
11966 VA = 50024.
VA = 4.18.
VA-12/86+VA-0/37+VA-4/90 = 0.
(90*37)*VA-(90*37)*12+(86*90)*VA+(37*86)*VA-(37*86)*4/(37*90*86) = 0.
11966 VA-50024 = 0.
11966 VA = 50024.
VA = 4.18.
