For the given figure(attached), the current drawn through the inductor is .9A while the current drawn through the condenser is .4A. Find the current drawn from the source.

Kirchoff's Current Law - the sum of the currents into a node must equal the sum of currents flowing out of that node. Take a look at the node on the right that connects the two components to the current source and apply Kirchoff's law.
