A current of 1.20 A reaches junction X. A current of 0.35 A leaves by one branch. The remaining current reaches junction Y, where a separate current of 0.15 A joins it. The current then divides into two branches; one carries 0.42 A. What does the other carry?
0.70 A0.70\ \mathrm{A}0.70 A
0.28 A0.28\ \mathrm{A}0.28 A
0.58 A0.58\ \mathrm{A}0.58 A
1.42 A1.42\ \mathrm{A}1.42 A
