R1 = 1Ω, R2 = 3Ω, connected in parallel. Total Current = 24A. Then V, I1, I2 =?

I have some questions about direct current circuitquestions

1. Three resistors connected in parallel have individual values of67.0, 6.0, and 10.0 ohms, repectively. If this combination isconnected in series with a 12.0V battery and a 2.0ohm resisotr.what is the current in the 10ohm resistor (in A)? (I got 1.15A butthe answer is 0.77A I coudlnt' figure out that why the current is0.77A)

2. Four resistors, R1,R2,R3, and R4, are arrayed as follows in awheatstone bridge circuit between four junction points, a,b,c andd: R1 is between points a and b; R2 is between b and c; R3 isbetween a and d; R4 is between c and d. A galvanometer and switchare connected in series between b and d. This system is connectedin series to a battery at points a and c. When R3=4 ohms and theratio R2/R4=3, the galvanometer reads zero current with the switchclosed. what is thevalue of R1 (in ohms) (the answer is 12.0A)

and if under the condition of zero galvanometer current, withswitch closed, the potenial difference across R4 is 3V, then whatis the voltage across R2(in V)? (answer is 3.0V)
