Solution

The correct option is C
$214 μ C, 27 V$

Given circuit can be redrawn as follows, because capacitors, $9 μ F, 9 μ F a n d 7 μ F$ are short circuited. So they can be removed.

$V_{1} + V_{2} = 40 V a n d \frac{V_{1}}{V_{2}} = \frac{36}{18} = 2$
Hence $V_{1} = \frac{80}{3} V a n d V_{2} = \frac{40}{3} V$
Charge on $8 μ F$ capacitor $= 8 \times \frac{80}{3} = 213.3 μ F \approx 214 μ F$
