Solution

REF.Image
as mercury is at same level, pressure exerted by water and spirit
along AB should be same. [P= hpg]
$\Rightarrow h_{1} p_{1} g = h_{2} p_{2} g$
$1 \to$ water
$2 \to$ spirit
$\Rightarrow p_{2} = \frac{h_{1} p_{1}}{h_{2}}$ for water, $p_{1} = 1 g / c c$
$= \frac{10 \times 1}{12.5} = 0.8 g / c c$
