Type: MCQ-numerical-Medium
A U-tube contains water and methylated spirit separated by mercury. The mercury column in the two arms are at the same level with 10 cm of water in one arm and 12.5 cm of spirit in the other as shown in figure. The relative density of the spirit is
A
0.6
B
0.8
C
1.0
D
1.25
Correct Answer
Option B
Detailed Explanation
