Free Sneak Peek

Here is a sneak peek of the questions included in this test set. Test your preparation by viewing the answer and detailed explanation before starting the timed exam.

Q1
For a pair of linear equations a_1 x + b_1 y + c_1 = 0 and a_2 x + b_2 y + c_2 = 0, what is the condition for them to have a unique solution (intersecting lines)?
रैखिक समीकरणों की एक जोड़ी के लिए a_1 x + b_1 y + c_1 = 0 और a_2 x + b_2 y + c_2 = 0, उनके लिए एक अद्वितीय समाधान (प्रतिच्छेदी रेखाएं) होने की क्या शर्त है?
A
\(a_1/a_2 = b_1/b_2 = c_1/c_2\)
B
a_1/a_2 \ne b_1/b_2
C
a_1/a_2 = b_1/b_2 \ne c_1/c_2
D
\(a_1/a_2 + b_1/b_2 = 0\)
Correct Answer: Option B
Explanation:
If a_1/a_2 \ne b_1/b_2, the lines intersect at a single point, yielding a unique solution (consistent system).
यदि a_1/a_2 \ne b_1/b_2, रेखाएं एक ही बिंदु पर प्रतिच्छेद करती हैं, जिससे एक अद्वितीय समाधान (सुसंगत प्रणाली) प्राप्त होता है।
Q2
What is the condition for a pair of linear equations in two variables to have infinitely many solutions (coincident lines)?
दो चर वाले रैखिक समीकरणों के एक युग्म के लिए अपरिमित रूप से अनेक समाधान (संपाती रेखाएँ) होने की क्या शर्त है?
A
a_1/a_2 \ne b_1/b_2
B
a_1/a_2 = b_1/b_2 \ne c_1/c_2
C
\(a_1/b_1 = a_2/b_2\)
D
\(a_1/a_2 = b_1/b_2 = c_1/c_2\)
Correct Answer: Option D
Explanation:
If a_1/a_2 = b_1/b_2 = c_1/c_2, the lines coincide, yielding infinitely many solutions (consistent/dependent system).
यदि a_1/a_2 = b_1/b_2 = c_1/c_2, रेखाएं संपाती होती हैं, जिससे अनंत रूप से कई समाधान (सुसंगत/आश्रित प्रणाली) प्राप्त होते हैं।

How Chapter-Wise Online CBT Tests Build Winning Habits for Future Competitive Exams

Early practice in high school builds the mental muscle, speed, and analytical discipline required to ace NTSE, Olympiads, JNVST, CUET, and Foundation JEE/NEET.

Competitive Edge

Real-Time Clock Awareness & Pacing

समय प्रबंधन एवं गति नियंत्रण

In school examinations, students write answers without active pacing. In national entrance tests, students have barely 45-60 seconds per MCQ. Practicing with a 20-minute timer instills instinctive time-budgeting and prevents last-minute exam panic.

Mastery of the Elimination Technique

विकल्प निष्कासन विधि में दक्षता

Top rankers in competitive exams rarely compute every problem blindly. They spot subtle traps, evaluate extreme values, and eliminate 2 out of 4 distractors within seconds. Our 4-option sets teach critical distractor analysis.

CBT Screen Stamina & Digital Comfort

कंप्यूटर आधारित परीक्षा का सहज अभ्यास

Almost all major national exams (CUET, JEE, NEET, SSC, Banking) are 100% computer-based. Students who only study on paper experience eye strain and navigation mistakes on exam day. Early CBT practice creates effortless digital fluency.

Immunity to Negative Marking

सटीकता और नकारात्मक अंकन से सुरक्षा

Careless errors—such as misreading "NOT" or "EXCEPT"—ruin thousands of competitive aspirations each year. Regular objective testing builds the habit of double-checking question keywords before locking answers.

Instant Diagnostic Feedback Loop

तत्काल त्रुटि निवारण एवं आत्म-मूल्यांकन

Traditional paper tests take weeks to grade, by which time the student has forgotten their thought process. TargetExams provides instant scorecards and step-by-step solutions while the conceptual puzzle is still fresh.
