Combination of Capacitors question from MHT CET 2025 (26 Apr, Shift 2)

Answer: (b)

1. Between P and R: path P–Q–R (2 in series, $\frac{C}{2}$) in parallel with path P–T–S–R (3 in series, $\frac{C}{3}$): $\frac{5C}{6}$.
2. Between P and Q: one $C$ in parallel with the other four in series ($\frac{C}{4}$): $\frac{5C}{4}$.
3. Ratio $= \frac{5C/6}{5C/4} = \frac{2}{3}$
4. So the answer is (b) $2 : 3$.
