For (y=0), how is the statement \(y\ge 0\)?
A. सत्यTrue
\(\ge\) में बराबरी शामिल होती है इसलिए \(0\ge 0\) सत्य है। सीमा मान को हमेशा ध्यान से जाँचें। / The sign \(\ge\) includes equality, so \(0\ge 0\) is true. Always check the boundary value carefully.

How do we write the sentence (m) is at least (50) as an inequality?
B. \(m\ge 50\)
कम से कम (50) का अर्थ (50) या उससे अधिक है। इसलिए सही असमानता \(m\ge 50\) है। / At least (50) means (50) or more. Therefore the correct inequality is \(m\ge 50\).

What is the correct form of the sentence (c) is not more than (75)?
B. \(c\le 75\)
अधिक नहीं है का अर्थ अधिकतम (75) है। अधिकतम वाले वाक्य में बराबरी शामिल होती है। / Not more than means at most (75). A maximum-type sentence includes equality.

If \(b\ge 10\), what happens after subtracting (6) from both sides?
A. \(b-6\ge 4\)
समान संख्या घटाने से चिह्न नहीं बदलता। घटाव में दिशा वही रहती है। / Subtracting the same number does not change the sign. In subtraction the direction remains the same.

If (p>6), what is the correct result after multiplying both sides by (3)?
A. (3p>18)
धनात्मक संख्या (3) से गुणा करने पर चिह्न नहीं पलटता। ऋणात्मक गुणा में ही दिशा बदलती है। / Multiplying by the positive number (3) does not reverse the sign. The direction changes only in negative multiplication.

If (q>2), what do we get after multiplying both sides by (-4)?
B. (-4q<-8)
ऋणात्मक संख्या से गुणा करने पर असमानता का चिह्न पलट जाता है। इसलिए (-4q<-8) सही है। / Multiplying by a negative number reverses the inequality sign. Therefore (-4q<-8) is correct.

What is the solution of \(x+9\le 15\)?
A. \(x\le 6\)
दोनों ओर (9) घटाने पर \(x\le 6\) मिलता है। जोड़ या घटाव से चिह्न नहीं बदलता। / Subtracting (9) from both sides gives \(x\le 6\). Addition or subtraction does not change the sign.

Which is the correct solution of (x-8>2)?
A. (x>10)
दोनों ओर (8) जोड़ने पर (x>10) मिलता है। घटे हुए पद को हटाने के लिए वही संख्या जोड़ें। / Adding (8) to both sides gives (x>10). Add the same number to remove the subtracted term.

What is the solution of \(4x\ge 20\)?
A. \(x\ge 5\)
दोनों ओर (4) से भाग देने पर \(x\ge 5\) मिलता है। धनात्मक भाग में दिशा नहीं बदलती। / Dividing both sides by (4) gives \(x\ge 5\). Division by a positive number does not change the direction.

Which value satisfies (3x+2<14)?
C. (x=3)
(x=3) रखने पर \(3\cdot3+2=11\) और (11<14) सत्य है। विकल्प को मूल असमानता में रखकर जाँचें। / For (x=3), \(3\cdot3+2=11\), and (11<14) is true. Check an option by substituting it in the original inequality.
