Gas Laws & Ideal Gas Equation

At constant temperature, increasing the pressure of a gas by $5\%$ its volume will decrease by

Show answer and solution

Answer: (d)

Boyle's law: $V \propto \dfrac{1}{P}$ at constant $T$ .
$P' = 1.05P \Rightarrow V' = \dfrac{V}{1.05} = 0.9524V$
Decrease $\approx 4.76\%$ , nearest option $4.70\%$ .
So the answer is (d) $4.70\%$ .
