x : y = 3 : 2 and (x² + y²) : (x² − y²) Assertion (A) : The value of (x² + y²) : (x² − y²) = 13 : 5 Reason (R) : x : y = 3 : 2 ⇒ (x² + y²) / (x² − y²) = (3k)² + (2k)² / (3k)² − (2k)² = 13/5 ; k ≠ 0 1. A is true, R is false. 2. A is false, R is true. 3. Both A and R are true and R is the correct reason for R. 4. Both A and R are true and R is the incorrect reason for R.
