perfect bro how?

first find current in circuit at 0.1ln2 sec.Let it be I1.After then make a new circuit with that 40 ohm resistor also in circuit(Initially it was shorted).Now write equation for current in the new circuit using kirchoff and integrate it from I1 to I.You will get the answer.

i got i1 as 5. what was your i1
