1/Rp=1/10+1/20+1/30+1/40
=24+12+8+6/240
=50/240
Rp=24/5=4.8ohm
V=12V
Rp=24/5
I=V/R
=12×5/24
=5/2=2.5A
Hope this is helpful.......

Total resistance in parallel,
1/Rp= 1/R1 + 1/R2 + 1/R3 + 1/R4
R1=10ohm
R2=40ohm
R3=30ohm
R4=20ohm
1/Rp= 1/10 + 1/40 + 1/30 + 1/20
1/Rp= (12 + 3 + 4 + 6)/120
1/Rp=25/120
1/Rp=5/24
Rp=4.8
total current,
i=v/r
i=12/4.8
i=2.5A
