it will depend on time taken by candles to burn completely.

If l unit is length of each candle and t is time taken by thinner candle to burn completely, and x is time elapsed when height of thinner is half the thicker one,then

2*(l-x*l/t)= (l-x*l(t+2))
solving
x= [t*(t+2)/(t+4)]

For example if t=4, then
x= 4*6/8= 3 hrs
after 3 hrs , length of thinner candle will be l/4 and length of thicker candle will be l/2.

check the other timmings if u want to be sure.
