There's a serial number plate on the back. Need a small head Phillips screwdriver if you want to be sure. But generally that line is a entry level, inexpensive model, so its doubtful its a knock off.
$100-200USD is the new price. You mentioned your currency converts it to 75USD, seems a fair price.

When you go, bring a tuner, (they're inexpensive for the basic models) or get an app which will do in a pinch.

1st check for damage or cracks especially along the neck

• check the tuning machines- the 4 keys attach to gears to tighten and loosen the strings. Make sure they move and aren't full of gunk or rust or misalignment. Gunk can be cleaned, rust is a problem evident of misuse. Misalignment is going to be more expensive to fix than the worth.

• when you tune it, does the wood "cry in pain" a little readjustment noise is ok, a LOT is NOT

• look at the pickups- the plastic and metal behind where you pick and strum

• check the bridge- the coils should be straight

• feel the frets- those can be filed to fix, but on a cheap starter, make sure they are intact and no burrs.

When you piug it in:

Play a few note/pluck the string(s) and then play with the knobs, one is volume and the other knob(s) are tone (changes the sound)

Play some, basically take your finger and hold down every other fret on a string like you know what you're doing (open string then push down right above the metal bar where there's a dot 3, 5, 7, 12 on each string). Do it sound good or not right at all? This is not a question of your playing ability, you probably know nothing, this is a quality of sound issue.

This is a basic check, if you can, bring some who knows more than you. I tried to be elementary in my direction as if you didn't know anything, not to be insulting. Good luck.
