Explanation opens after your attempt
Correct Answer

A. (x+4y=6) और (2x+8y=13)(x+4y=6) and (2x+8y=13)

Step 1

Concept

In the first option (1/2=4/8) but (6/13) is different. Therefore the lines are distinct parallel.

Step 2

Why this answer is correct

The correct answer is A. (x+4y=6) और (2x+8y=13) / (x+4y=6) and (2x+8y=13). In the first option (1/2=4/8) but (6/13) is different. Therefore the lines are distinct parallel.

Step 3

Exam Tip

पहले विकल्प में (1/2=4/8) लेकिन (6/13) अलग है। इसलिए रेखाएं अलग समानांतर हैं।

नीचे में से कौन-सा युग्म संगत और आश्रित है?

Which of the following pairs is consistent and dependent?

Explanation opens after your attempt
Correct Answer

B. (x-2y=5) और (3x-6y=15)(x-2y=5) and (3x-6y=15)

Step 1

Concept

In the second option the second equation is (3) times the first. Therefore both are the same line and the pair is dependent.

Step 2

Why this answer is correct

The correct answer is B. (x-2y=5) और (3x-6y=15) / (x-2y=5) and (3x-6y=15). In the second option the second equation is (3) times the first. Therefore both are the same line and the pair is dependent.

Step 3

Exam Tip

दूसरे विकल्प में दूसरा समीकरण पहले का (3) गुना है। इसलिए दोनों एक ही रेखा हैं और युग्म आश्रित है।

समीकरण (2x+3y=5) और (4x+6y=10) को देखकर सबसे तेज निष्कर्ष क्या है?

What is the quickest conclusion by observing (2x+3y=5) and (4x+6y=10)?

Explanation opens after your attempt
Correct Answer

C. दूसरा पहले का (2) गुना है इसलिए अनंत हल हैंThe second is (2) times the first so infinitely many solutions
