Here ,both bulbs are connected in parallel combination .So voltage of both the bulbs are same. Power is inversely proportion to the resistance of the wire(P=V square/R). So the bulb which have low resistance having more power .Bulbs which have more power glow more.. Resistance of 1st bulb P=60 V=220 R= 220*220* 60=806.6ohm Resistance of 2nd bulb P=80 V=220 R=220*200/80=605ohm Here ,the resistance of 2nd bulb is low so power of 2nd bulb is more.Second bulb rated 80W,220V glow more..
