An iceberg is floating partly immersed in sea water, the density of sea water is `1.03 g cm^(-3)` and that of ice is `0.92 g cm^(-3)`. The fraction of the total volume of the iceberg above the level of sea water is

Options

A. ` 8.1%`
B. `11%`
C. `34%`
D. `0.8%`

Answer

B

Explanation

Let v be the volume of the ice-berg outside the sea water and V be the total volume of ice-berg. Then as per quesiton
` 0.92 V = 1. 03 (V-v) or v//v v =1 -0.92//1.03 =11//103`
`therefore (v //v) xx 100 = 11 xx 100 // 103 ~~ 11%`
