किस धनात्मक संख्या में (6) जोड़कर उसे मूल संख्या से गुणा करने पर (135) मिलता है?

For which positive number does adding (6) and multiplying by the original number give (135)?

Explanation opens after your attempt
Correct Answer

A. (9)

Step 1

Concept

If the number is (x), then (x(x+6)=135). From \(x^2+6x-135=0\), (x=9).

Step 2

Why this answer is correct

The correct answer is A. (9). If the number is (x), then (x(x+6)=135). From \(x^2+6x-135=0\), (x=9).

Step 3

Exam Tip

यदि संख्या (x) है, तो (x(x+6)=135)। \(x^2+6x-135=0\) से (x=9) है।
