Assertion (A): If x > y, x + y = 6 and x - y = 2 then x² + y² = 40

Reason (R): (x + y)² + (x - y)² = 2(x² + y²)

1. A is true, but R is false.

2. A is false, but R is true.

3. Both A and R are true, and R is the correct reason for A.

4. Both A and R are true, and R is the incorrect reason for A.

Assertion (A): 5³ - 3³ - 2³ = 3 x 5 x -3 x -2

Reason (R): ∵ 5 - 3 - 2 = 0

⇒ 5³ - 3³ - 2³ = 5³ + (-3)³ + (-2)³

1. A is true, but R is false.

2. A is false, but R is true.

3. Both A and R are true, and R is the correct reason for A.

4. Both A and R are true, and R is the incorrect reason for A.
