A constant immersion hydrometer weighing 20 g sinks upto mark 'x' in water and this hydrometer has to weight 25 g to mark 'x' in a given liquid. Then the relative density of the liquid is ____.

A

`0.25`

B

`1.25`

C

`0.75`

D

`2.00`

Text Solution

Verified by Experts

The correct Answer is:
B

R.D=`("weight of hydrometer in liquid")/("Weight of hydrometer in water") =25/20=1.25`
