Hi!

I have opted for the 2 month study plan and came across this problem in one of the videos. I didn’t follow why r<= -5 was not considered. Can someone please help me with the logic here?

That’s because r <= -5 is included in r <= (25/3).

According to question we have to see which value r won’t be able to take so clearly we will take larger set values.

For instance, if some one ask you what value “p” can take and they give inequalities as

p <= 2 and p <= 4

so obviously you will look at p <= 4 because p can take value as 3 too (if integer ) which is not included in p <= 2.

Thank you.
