mass of 'A' is Ma

mass of 'B' is Mb

both of them undergo an accelaration of 'g' as it is falling from a height

initial velocity of both is zero as it is dropped from rest.

From 2nd equation of motion.

S = 1/2 a t2                      [ since u = 0 , it is not taken. ]

a = 1/2g t12

b = 1/2g t22

a/b = t12 / t22

t1 / t2 = √a/b

 

this the the ratio of times taken by Ma and Mb
