Dear Sunny,

(i) Initial flux = nBiA = 50*7*10-2*200*10-4 Wb = 7*10-2 Wb
(ii) Final flux = nBfA = 50*2*10-2*200*10-4 Wb = 2*10-2 Wb
(iii) EMF = ΔΦ/Δt = 5*10-2/0.04 V = 1.25 V


Please feel free to post as many doubts on our discussion forum as you can.we will get you the answer and detailed  solution very  quickly. All the best.
