U-tube contains some amount of mercury. Immiscible liquid X is poured in the left arm and immiscible liquid Y is poured in the right arm. Length of liquid X is 8 cm, length of liquid Y is 10 cm and upper levels of X and Y are equal. If density of Y is $$3.36\text{ g cm}^{-3}$$ and density of mercury is $$13.6\text{ g cm}^{-3}$$, then density of X is

A

$$0.8\text{ g cm}^{-3}$$

B

$$1.2\text{ g cm}^{-3}$$

C

$$1.4\text{ g cm}^{-3}$$

D

$$1.6\text{ g cm}^{-3}$$
