UPSEE Solved Model Paper 3

Let BP and BQ be the magnetic field produced by the wire P and Q which are placed symmetrically in a rectangular loop ABCD as shown in figure. Current in wire P is I directed inward and in Q is 2 I directed outwards. If
∫ABBQ.dl = +2µ0T−m , ∫DABP.dl = −2µ0T−m and ∫ABBP.dl = −µ0T−m.
the value of I will be
