Solution

The correct option is C
3

It is given that, $E f f o r t d i s t a n c e = 3 \times L o a d d i s t a n c e$ .

Plugging this value of effort distance in the formula of V.R. we get,

$V . R = \frac{E f f o r t d i s t a n c e}{L o a d d i s t a n c e} = \frac{3 \times L o a d d i s t a n c e}{L o a d d i s t a n c e} = 3$
