```										dear rohit,
let initial difference in height of mercury level = h2=200mm
n sp. gravity of mercury = 13.6
sp. gravity of water = 1.0
therefore
density of water = 1000
density of mercury = 1360
using equation,
d1*g*h1= d2*g*h2
=> h1= 272 mm of water
when the vessel is full ofwater the pressure in the right limb will go down and lhe distance moved by mercury level be y  cm
above the datum level,
again equating pressure on boyh sides,
13.6*1000*9.81*(0.2*2y/100) = 1000*9.81 * (3+ y/100 + h1 )
=> y= 11.45 cm
difference in two limbs of mercury = 20+2y = 42.9 cm = 429 mm

```										As we have converted y cm to y in meters by dividing it with 100, then how can we get answer in cm?Can anyone clear this ambiguity?
