In a meter bridge experiment, two resistances $X$ and $Y$ in the two gaps give a null point dividing the wire in the ratio $2 : 3$. When each resistance is increased by $30 \text{ } \Omega$, the null point divides the wire in the ratio $5 : 6$. The resistances $X$ and $Y$ are respectively:

• A
  $20 \text{ } \Omega, 30 \text{ } \Omega$
• B
  $22 \text{ } \Omega, 33 \text{ } \Omega$
• C
  $32 \text{ } \Omega, 48 \text{ } \Omega$
• D
  $40 \text{ } \Omega, 60 \text{ } \Omega$
