Hi Rittu, the symbols in the question are fine.

try squinting

Hi Kajal
The question says, "The number of integers n satisfying $$-n+2\ge\ 4$$ and $$2n\ge\ 4$$ is"
This means that the question asking how many values of n are possible such that they satisfy both the inequalities.
Since, only one value of n (that is n=2) is possible, the answer to this question is 1.
Hope this helps, please let us know if any doubts persist!

Hi Paawan,

Integers greater than 2 will not satisfy $$-n+2\ge 0$$, as $$-n+2$$ will always be a negative number then.

Hope this helps, feel free to ask if you have any questions
