Correct option is A- -65- wattThe two bulbs of 100W and 200W are working at 220V are joined in series with 220V supply-160-Thus -P-s-dfrac-P-1-P-2-P-1-P-2-dfrac-100-times 200-100-200-dfrac-200-3-approx 65watt-

Two bulbs of $$100 W$$ and $$200 W$$ working at $$220$$ volt are joined in series with 220 volt supply. Total power consumed wll be approximately.

Correct option is A. $$65$$ watt
The two bulbs of 100W and 200W are working at 220V are joined in series with 220V supply
Thus ,$$P_{s}=\dfrac{P_{1}P_{2}}{P_{1}+P_{2}}=\dfrac{100\times 200}{100+200}=\dfrac{200}{3}\approx 65watt$$
