The resistances of the four arms P,Q,R and S in a Wheatstone’s bridge

The resistances of the four arms P,Q,R and S in a Wheatstone’s bridge are 10Ω, 30Ω, 30Ωand 90Ω respectively. The emf and internal resistance of the cell are 7V and 5Ω, respectively. If the galvanometer resistance is 50Ω, then the current drawn from the cell will be
