Question

Two resistors of 30 and 60 ohms are connected in parallel. How does the current passing through the two resistors compare?

Answer 1

As being in Parallel, the Potential Difference will be same. Different will be the Current
So Current for 30 ohm resistor will be $\frac{V}{30}$ Ampere
And Current for 60 ohm resistor will be $\frac{V}{60}$ Ampere

The ratio of the Currents will be $\frac{I_{1}}{I_{2}}= \frac{V}{30}* \frac{60}{V}= \frac{2}{1}$

Therefore, the Current for first resistor is double the current for second resistor

Answer 2

The  Potential Difference (p.d) will be same

But there will be a difference in the current flowing
Potential difference = V
Resistance = 30Ω
Current = V/30 Ampere


-------------------------------
Resistance = 60Ω
Current = V /60 Ampere

we know that Current is inversely proportional to the current flowing.
hence , when the resistance is more , current flowing is less .
when resistance is less , current flowing is more .

so , 
30 Ω  < 60Ω

current passing through the resistor 60Ω will be less than current passing through the resistor 30Ω .

Current passing through resistor 30 ohm is double than current passing through 60 ohm resistor .
