समीकरणों (ax+4y=10) और (6x+8y=25) का कोई हल न होने के लिए (a) का मान क्या होगा?

What is the value of (a) for the equations (ax+4y=10) and (6x+8y=25) to have no solution?

Explanation opens after your attempt
Correct Answer

B. (3)

Step 1

Concept

For no solution, (a/6=4/8) and (10/25) must be different. This gives (a=3).

Step 2

Why this answer is correct

The correct answer is B. (3). For no solution, (a/6=4/8) and (10/25) must be different. This gives (a=3).

Step 3
