Two bodies are projected from ground with same speeds $\displaystyle 40 \mathrm{~ms}^{-1}$ at two different angles with respect to horizontal. The bodies were found to have same range. If one of the body was projected at an angle of $\displaystyle 60^{\circ}$, with horizontal then sum of the maximum heights, attained by the two projectiles, is $\displaystyle \_\_\_\_$ m. (Given $\displaystyle \mathrm{g}=10 \mathrm{~ms}^{-2}$ )
