THIS VIDEO IS NOT FOR BEGINNERS

I feel like someone with no mathematical background would hate quant just from watching this video.
This is for Intermediate to advanced people.
If you aren't please don't watch first watch other videos then come here. I had to watch it twice. First time I did not understand anything.
second time after doing practice questions, I understood what he was talking about. And the video will help a lot.

READ THE QUESTION WRONG!!!
IT IS ASKING DIFFERENT FACTORS=> NOT DIFFERENT PRIME FACTORS.

*TRICK QUESTION. "IF a and b are prime numbers, a CAN B equal to b"
if a=b, then n+2 is ans {3+2=5}
if a not equal to b=> 1+1 *n+1=> 2n+2 ans {6+2=8}

HENCE E

Sq. root 3 + Sq. root 7 + Sq. root 10 equals 7.54 So shouldn't rounding down give the answer 7 (E)?
