2T force will act on 4k spring
and again 2T force will be acting on 8k spring.
expansion  in 4k spring=2T/4k=T/2k........1
expansion  in 8k spring=2T/8k=T/4k=half of upper spring.........2
then apply constraint equations to find the net acceleration etc,which is not at all in the course of NCERT or JEE(mains)
