When resistances are connected in series, same current passes through each of them. So power (P) & potential difference across resistance are, P is proportional to R(resistance) [ as P=(i^2)*R] V is proportional to R(resistance) [ as P=i*R] i.e., in series connection, power consumed & P.D. will be more in higher resistance.
Higher wattage means less resistance, when a number of bulbs are connected in series, a bulb with lower resistance will consume less power & the P.D. across it will also be less. Therefore in series connection, a bulb with higher wattage will glow less brightly.
Hence the 10W bulb will glow brighter.Hope this might help you
