On the number line, (x) is (2.5) units to the left of (1). What is the value of (x)?
B. (-1.5)
बाईं ओर जाने पर (x=1-2.5=-1.5) होगा। परीक्षा में बाईं दिशा को घटाव से जोड़ें। / Moving left gives (x=1-2.5=-1.5). In exams, connect left direction with subtraction.

Between which two integers will \(\sqrt{27}\) lie on the number line?
C. (5) और (6)(5) and (6)
क्योंकि \(5^2=25\) और \(6^2=36\), इसलिए \(\sqrt{27}\) (5) और (6) के बीच है। परीक्षा में निकट पूर्ण वर्गों को याद रखें। / Since \(5^2=25\) and \(6^2=36\), \(\sqrt{27}\) lies between (5) and (6). In exams, remember nearby perfect squares.

Between which two integers will \(-\sqrt{30}\) lie on the number line?
B. (-6) और (-5)(-6) and (-5)
क्योंकि \(\sqrt{30}\) (5) और (6) के बीच है, इसलिए \(-\sqrt{30}\) (-6) और (-5) के बीच होगा। परीक्षा में ऋणात्मक दिशा को ध्यान रखें। / Since \(\sqrt{30}\) lies between (5) and (6), \(-\sqrt{30}\) lies between (-6) and (-5). In exams, keep the negative direction in mind.

Between which two integers will \(3\sqrt{2}\) lie on the number line?
B. (4) और (5)(4) and (5)
\(3\sqrt{2}\) लगभग (4.24) है, इसलिए यह (4) और (5) के बीच है। परीक्षा में \(\sqrt{2}\) को लगभग (1.414) मानकर अनुमान लगा सकते हैं। / \(3\sqrt{2}\) is about (4.24), so it lies between (4) and (5). In exams, you may estimate \(\sqrt{2}\) as about (1.414).

Which statement is correct on the number line?
C. \(-\sqrt{2}\) (0) के बाईं ओर है\(-\sqrt{2}\) is to the left of (0)
\(-\sqrt{2}\) ऋणात्मक है, इसलिए यह (0) के बाईं ओर होगा। परीक्षा में चिह्न देखकर दिशा तय करें। / \(-\sqrt{2}\) is negative, so it lies to the left of (0). In exams, decide direction from the sign.
