A mass M, attached to a horizontal spring executing S.H.M with amplitude A1. When themass M passes through its mean position then a smaller mass m is placed over it andboth of them move together with amplitude A2. The ratio of 12AA???????? is?

Total energy of string being stretched = E = 1/2kx²
energy of string with amplitude = E = 1/2k (A1)²
E is also the kinetic energy 
M is the mean position
As E is the independent mass so, energy remains the same
so it will be
A1 = A2
or 1: 1
