The 60W bulb will fuse. Because it has a power of only 60W and 440V is higher than its capability.
First find the current in 60w bulb then find another current in 100w bulb then find the indiviual resistance of 60w and 100w bulb then find the total current in the circuit and see which of the current  has less ampere flowing through the bulb that bulb will fuse and similarily do that in 440v potential difference this happens because the current is excessively has less ampere and therfore the bulb fuse because of high resistance and its heating effect
