किस अंतराल में (5) शामिल नहीं है लेकिन (5) से छोटी सभी संख्याएँ शामिल हैं?
Which interval does not include (5) but includes all numbers less than (5)?
Explanation opens after your attempt
A. (\(-\infty,5\))
Concept
Since (5) is not included, a parenthesis is used, and smaller numbers extend toward \(-\infty\). Hence (\(-\infty,5\)) is correct.
Why this answer is correct
The correct answer is A. (\(-\infty,5\)). Since (5) is not included, a parenthesis is used, and smaller numbers extend toward \(-\infty\). Hence (\(-\infty,5\)) is correct.
Exam Tip
(5) शामिल नहीं है इसलिए गोल कोष्ठक लगेगा और छोटी संख्याएँ \(-\infty\) की ओर होंगी। इसलिए (\(-\infty,5\)) सही है।
