The size of a quasar can be inferred from the timescale of variations in its light output.
Assuming that no signal can travel across the source faster than the speed of light, the
time scale of the fastest variations sets an upper limit on the size of the quasar (i.e., size quals approximately the variation timescale times speed of light).
An alternative method called 'reverberation mapping' monitors changes in the quasar's light output, then looks for these same changes in the light output from specific spectral lines. The delay times the speed of light gives the size of the quasar.

What does a black hole do with what it suck in?
The material sucked in to a black hole becomes part of the black hole - that is, a black hole crushes matter to an nearly no size, at all.
How can the mass of a black hole can be measured?
The mass of a black hole can be measure by the effects of its gravity on surrounding objects.
Can 8 earth's fit in the black hole?
yes and no depends on size of hole :]
Does a medium size star become black holes?
The size of a black hole, as defined by the size of the event horizon, depends on the mass of the black hole and its electrical charge. The diameter of the event horizon is directly proportional to the black hole's mass. Adding electrical charge decreases the size of the event horizon.
What would happen if two black hole were to merge into each other?
You would have a black hole the size of the combined mass of the two black holes.

What happens after entering a black hole?
Any matter that enters the black hole will be destroyed. Also, it will increase the black hole's size.
Can a black hole get to the size of a planet?
A black hole can definitely get to the size of a planet. The width of the largest known supermassive black hole is thought to be over ten times the size of the entire orbit of Neptune around our Sun.
How can the mass of a black hole can be measured?
The mass of a black hole can be measure by the effects of its gravity on surrounding objects.
Is there a maximum size limit to a black hole?
No.

yes and no depends on size of hole :]

What would happen if two black hole were to merge into each other?
You would have a black hole the size of the combined mass of the two black holes.
What is the minimum and maximum size of the black hole?
There isn't one. It depends on how much matter the collapsed star (black hole) has gathered.
Is an Intermediate-mass black hole a type of black hole?
Yes. Intermediate-mass blackhole is a medium size black hole. Scientists have found stellar black holes and supermassive black holes but there is no prove that Intermediate-mass black type of black holes exist. My opinion is that they do exist because when a black hole is becoming a black hole supermassiveblack hole it will need to go though this stage of intermediate-mass black hole.
Does the sucking of masses increase the size of a black hole?
yes
What is the size of a black hole?
about 1/3 of a neutron star
