What is the correct solution of \(\frac{5-x}{2}>4\)?
A. (x<-3)
(5-x>8) से (-x>3) और (x<-3) मिलता है। (-1) से भाग देने पर चिन्ह बदलना याद रखें। / From (5-x>8), we get (-x>3) and (x<-3). Remember to reverse the sign when dividing by (-1).

If (x) is a natural number and \(3x-2\leq 13\), how many values of (x) are possible?
A. (5)
\(3x\leq 15\) से \(x\leq 5\) मिलता है। प्राकृतिक मान (1,2,3,4,5) हैं। / From \(3x\leq 15\), we get \(x\leq 5\). The natural values are (1,2,3,4,5).

Which is the solution set of \(4x+3\geq 2x-5\)?
A. \({x:x\geq -4}\)
\(2x\geq -8\) इसलिए \(x\geq -4\) है। समुच्चय रूप में चर की शर्त साफ लिखें। / Since \(2x\geq -8\), \(x\geq -4\). In set form, write the condition on the variable clearly.

What do we get after solving \(6-5x\leq 16\)?
A. \(x\geq -2\)
\(-5x\leq 10\) में (-5) से भाग देने पर \(x\geq -2\) होता है। ऋणात्मक भाग से चिन्ह पलटता है। / In \(-5x\leq 10\), dividing by (-5) gives \(x\geq -2\). Division by a negative number reverses the sign.

Choose the correct solution of (8x-3<5x+12).
A. (x<5)
(3x<15) से (x<5) मिलता है। सीमा बिंदु (5) शामिल नहीं है। / From (3x<15), we get (x<5). The boundary point (5) is not included.

What is the solution of (11-4x>3)?
A. (x<2)
(-4x>-8) में (-4) से भाग देने पर (x<2) मिलता है। खुले चिन्ह का अर्थ सीमा शामिल नहीं है। / In (-4x>-8), dividing by (-4) gives (x<2). The strict sign means the boundary is not included.

For which (x) is (5(2x-1)\leq 3x+16) true?
A. \(x\leq 3\)
\(10x-5\leq 3x+16\) से \(7x\leq 21\) और \(x\leq 3\) मिलता है। विस्तार के बाद सरल करें। / From \(10x-5\leq 3x+16\), we get \(7x\leq 21\) and \(x\leq 3\). Expand and then simplify.

What is the solution of (2(3x+4)>4x+18)?
A. (x>5)
(6x+8>4x+18) से (2x>10) और (x>5) मिलता है। सख्त असमानता में बराबरी नहीं आती। / From (6x+8>4x+18), we get (2x>10) and (x>5). A strict inequality does not include equality.
