Hey Mate

your answer is ---

Given, two bulb one is 100watt and second is 60watt , both are connected in parallel series so, potential difference in both bulb is same

now , current in 100watt bulb is

according to formula

P = VI

=> I = 100/220

=> I = 0.45ampere

now, current in 60watt bulb is

I = 60/220 = 0.27ampere

therefore , total current is 0.27+0.45 =0.72ampere (approx)
