यदि (3x+2y=25) और (x-y=1), तो (x+y) का मान क्या है?

If (3x+2y=25) and (x-y=1), what is the value of (x+y)?

Explanation opens after your attempt
Correct Answer

C. \(\frac{49}{5}\)

Step 1

Concept

Using (x=y+1) gives (5y+3=25), so \(y=\frac{22}{5}\) and \(x=\frac{27}{5}\). Hence \(x+y=\frac{49}{5}\).

Step 2

Why this answer is correct

The correct answer is C. \(\frac{49}{5}\). Using (x=y+1) gives (5y+3=25), so \(y=\frac{22}{5}\) and \(x=\frac{27}{5}\). Hence \(x+y=\frac{49}{5}\).

Step 3

Exam Tip

(x=y+1) रखने पर (5y+3=25), इसलिए \(y=\frac{22}{5}\) और \(x=\frac{27}{5}\)। अतः \(x+y=\frac{49}{5}\)।
