A solid whose volume does not change with temperature, floats in a liq

1.	A solid whose volume does not change with temperature, floats in a liquid. Fractions f_1 and f_2 of its volume remain submerged fortwo different temperatures t_1 and t_2 of liquid. The volume coefficient of expansion of liquid is
Answer» `( f_1 + f_2)/( f_1 t_1 + f_2 t_2)` `( f_1 + f_2)/( f_2 t_1 + f_1 t_2)` `( f_1 - f_2)/( f_1 t_1 + f_2 t_2)` `( f_1 - f_2)/( f_2 t_1 - f_1 t_2)` ANSWER :D
