Each bulb has power 1.5W.
As
We get the resistance of each bulb as 13.5. Now as the bulbs are arranged in parallel, the effective resistance of the circuit will be 13.5÷3=4.5 ohms.
Now we have got the resistance as well as the voltage supplied. By using formula
We get the current as 1

how you got 4.5 ohms as resistance
The reciprocal of the effective resistance is equal to the sum of reciprocals of individual resistances. So the reciprocal of effective resistance becomes 3/13.5
