Correct Answer: Option B

Explanation

Wt. in air = 0.25 N
Wt.in water = 0.15 N
Therefore, lost in wt. in water = Upthrust in water
= 0.25 - 0.15
= 0.10 N.
Wt. in paraffin oil = 0.17 N.
.. loss in wt. in oil = upthrust in the oil = 0.25 - 0.17 = 0.08
Ratio of upthrust in oil to upthrust in water
= \(\frac{0.08}{0.10}\) = \(\frac{8}{10}\) = \(\frac{4}{5}\) Or 4 : 5
