A \(x>-\frac{12}{5}\)
B \(x<-\frac{12}{5}\)
C \(x\ge -\frac{12}{5}\)
D \(x\le -\frac{12}{5}\)
Explanation opens after your attempt
Correct Answer
B. \(x<-\frac{12}{5}\)
Step 1
Concept
Clearing denominators gives \(20x+30<15x+18\). Thus \(5x<-12\), so \(x<-\frac{12}{5}\).
Step 2
Why this answer is correct
The correct answer is B. \(x<-\frac{12}{5}\). Clearing denominators gives \(20x+30<15x+18\). Thus \(5x<-12\), so \(x<-\frac{12}{5}\).
Step 3
Exam Tip
हर हटाने पर \(20x+30<15x+18\) मिलता है। इससे \(5x<-12\), इसलिए \(x<-\frac{12}{5}\) है।

#class-11
#expert
A \(x\ge 14\)
B (x>7)
C (7<x<14)
D \(x\le 14\)
Explanation opens after your attempt
Correct Answer
A. \(x\ge 14\)
Step 1
Concept
The first inequality gives \(x\ge 14\), and the second gives (x>7). Their intersection is \(x\ge 14\).
Step 2
Why this answer is correct
The correct answer is A. \(x\ge 14\). The first inequality gives \(x\ge 14\), and the second gives (x>7). Their intersection is \(x\ge 14\).
Step 3
Exam Tip
पहली असमानता से \(x\ge 14\) और दूसरी से (x>7) मिलता है। प्रतिच्छेद \(x\ge 14\) है।

युग्म असमानता \(-4\le 5-3x<11\) को हल कीजिए।
Solve the compound inequality \(-4\le 5-3x<11\).
#linear-inequalities
#negative-coefficient
#class-11
#expert
A \(x\le -2\)
B (x>3)
C \(-2<x\le 3\)
D \(-2\le x<3\)
Explanation opens after your attempt
Correct Answer
C. \(-2<x\le 3\)
Step 1
Concept
Solving both sides separately gives \(x\le 3\) and (x>-2). Therefore \(-2<x\le 3\) is the correct interval.
Step 2
Why this answer is correct
The correct answer is C. \(-2<x\le 3\). Solving both sides separately gives \(x\le 3\) and (x>-2). Therefore \(-2<x\le 3\) is the correct interval.
Step 3
Exam Tip
दोनों तरफ अलग-अलग हल करने पर \(x\le 3\) और (x>-2) मिलता है। इसलिए \(-2<x\le 3\) सही अंतराल है।

युग्म असमानता \(3x-8<2x+1\le 5x-11\) का हल क्या है?
What is the solution of the compound inequality \(3x-8<2x+1\le 5x-11\)?
#linear-inequalities
#double-inequality
#class-11
#expert
A (x<4)
B \(4\le x<9\)
C \(x\ge 9\)
D \(4<x\le 9\)
Explanation opens after your attempt
Correct Answer
B. \(4\le x<9\)
Step 1
Concept
The first part gives (x<9), and the second gives \(x\ge 4\). Combining both gives \(4\le x<9\).
Step 2
Why this answer is correct
The correct answer is B. \(4\le x<9\). The first part gives (x<9), and the second gives \(x\ge 4\). Combining both gives \(4\le x<9\).
Step 3
Exam Tip
पहले भाग से (x<9) और दूसरे भाग से \(x\ge 4\) मिलता है। दोनों को मिलाकर \(4\le x<9\) मिलता है।

असमानता \(\frac{2x-5}{3}+\frac{x+1}{6}\le \frac{x}{2}\) का हल क्या है?
What is the solution of \(\frac{2x-5}{3}+\frac{x+1}{6}\le \frac{x}{2}\)?
#linear-inequalities
#fraction-sum
#class-11
#expert
A \(x\ge \frac{9}{2}\)
B \(x<\frac{9}{2}\)
C \(x>\frac{9}{2}\)
D \(x\le \frac{9}{2}\)
Explanation opens after your attempt
Correct Answer
D. \(x\le \frac{9}{2}\)
Step 1
Concept
Clearing denominators gives \(5x-9\le 3x\). This gives \(2x\le 9\), so \(x\le \frac{9}{2}\).
Step 2
Why this answer is correct
The correct answer is D. \(x\le \frac{9}{2}\). Clearing denominators gives \(5x-9\le 3x\). This gives \(2x\le 9\), so \(x\le \frac{9}{2}\).
Step 3
Exam Tip
हर हटाने पर \(5x-9\le 3x\) मिलता है। इससे \(2x\le 9\) और \(x\le \frac{9}{2}\) आता है।
