Two tangent galvanometer P and Q differ only in the number of turns of their coils and are connected in series. On passing a current through them, the deflections in P and Q are found to gbe 45^(@) and 35^(@) respectively. Calculate the ratio of the number of turns

Two tangent galvanometer A and B differing only in the number of turns in their coils are connected in series. On passing a current through them, the deflections in A and B are 40^(@) and 26.5^(@) respectively. Calculate the ratio of their numbers of turns.

Two tangent galvanometers, which are identical except in their number of turns are connected in parallel. The ratio of their resistances of the coils is 1 : 3 . If the deflections in the two tangent galvanometers are 30^(@) and 60^(@) respectively, then the ratio of their number of turns is
