how come d ratio of max heights is m?
two bodies have a mass ratio m. They are thrown from a tower to another with the same initial conditions. The ratio of their heights is also m. What is the ratio of their times of flight!?

Two bodies have a mass ratio and height ratio as m.
Here mass ratio is irrevelant, so we ignore it. Kinematics does not deal with mass.
Height ratio is m.
Hence, H1 / H2 = U12 / U22
where H means height and U means initial speed.
Also, U1 / U2 = T1 / T2
From this, we can infer that Height is directly proportional to the square of time.
Hence,
H1 / H2 = M (ratio) = T12 / T22
This means that the Time ratio is the square root of Height ratio.
That is,
T1 / T2 = √M
Hence all the given options in the question were wrong.
