Ok I can't give you some insane explanation but I think what i'm about to tell you is more valuable. These questions are probably the nicest ones out there. This is a spring harmonic so we know T=2π√(M/K).Just put some random but fair sized constant value for K, as we know this isn't changing and adjust M till you get 1.5T.

The beauty is this sort of method is perfect for multi choice as you aren't bound to method marks or anything like that. If you can spot the equation that you need to use, try putting in some realistic values and change what they want you to change. However, YMMV!!

Isn't there a different way that I could be used?

basically if you add 1.25 u get 2.25 and since t is proportional to root of m then root of 2.25 = 1.5 so its c

Since T is proportional to sqrt M
T2/T1 = sqrt(M2/M1)
1.5 = sqrt(M2/1)
M2 = 2.25
Thus , we need another 1.25 added to the 1 kg
