In a metre bridge experiment null point is obtained at $\displaystyle 40$ cm from one end of the wire when resistance $\displaystyle X$ is balanced against another resistance Y. If X < Y, then the new position of the null point from the same end, if one decides to balance a resistance of 3X against Y, will be close to :
Official answer
(3)
$\displaystyle 67$ cm
