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

In the given figure, line $AB \parallel CD$ and transversal $EF$ intersects them. Two consecutive interior angles on the same side of the transversal are $(2x + 10)^\circ$ and $(3x + 20)^\circ$. What is the value of $x$?

തന്നിരിക്കുന്ന ചിത്രത്തിൽ, $AB \parallel CD$ എന്നീ സമാന്തര വരകളെ $EF$ എന്ന ഛേദകം ഖണ്ഡിക്കുന്നു. ഛേദകത്തിന്റെ ഒരേ വശത്തുള്ള സഹ-ആന്തര കോണുകൾ $(2x + 10)^\circ$, $(3x + 20)^\circ$ എന്നിവയാണെങ്കിൽ, $x$-ന്റെ വില എത്രയാണ്?

A

25

B

30

C

35

D

40

Correct Answer: Option B

Explanation:

Consecutive interior angles on the same side of a transversal are supplementary: $(2x + 10) + (3x + 20) = 180^\circ \implies 5x + 30 = 180^\circ \implies 5x = 150^\circ \implies x = 30$.

ഒരു ഛേദകത്തിന്റെ ഒരേ വശത്തുള്ള സഹ-ആന്തര കോണുകളുടെ തുക $180^\circ$ ആണ് (അനുപൂരകങ്ങൾ): $(2x + 10) + (3x + 20) = 180^\circ \implies 5x + 30 = 180^\circ \implies 5x = 150^\circ \implies x = 30$.

Q2

In the given figure, two parallel lines are cut by a transversal. A pair of alternate interior angles are given as $(3y - 15)^\circ$ and $(y + 45)^\circ$. What is the actual degree measure of these alternate angles?

തന്നിരിക്കുന്ന ചിത്രത്തിൽ, രണ്ട് സമാന്തര വരകളെ ഒരു ഛേദകം ഖണ്ഡിക്കുന്നു. മറുക്കോണുകളുടെ ഒരു ജോടി $(3y - 15)^\circ$, $(y + 45)^\circ$ എന്നിവയാണെങ്കിൽ, ഈ മറുക്കോണുകളുടെ കൃത്യമായ അളവ് എത്ര ഡിഗ്രിയാണ്?

A

60°

B

30°

C

45°

D

75°

Correct Answer: Option D

Explanation:

Alternate interior angles are equal: $3y - 15 = y + 45 \implies 2y = 60 \implies y = 30$. Measure of the angle $= y + 45 = 30 + 45 = 75^\circ$.

സമാന്തര വരകളെ ഒരു ഛേദകം ഖണ്ഡിക്കുമ്പോൾ ഉണ്ടാകുന്ന മറുക്കോണുകൾ തുല്യമാണ്: $3y - 15 = y + 45 \implies 2y = 60 \implies y = 30$. അതിനാൽ കോണിന്റെ അളവ് $= 30 + 45 = 75^\circ$.

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

Early practice in middle school builds the mental muscle, speed, and analytical discipline required to ace NTSE, Olympiads, JNVST, Sainik School, and Future Competitive Exams.

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.
