If ⁿ ⁺ ¹C₃ = 3.ⁿ C₂, then the value of n is
Choice (d) is correct. Given, ⁿ ⁺ ¹C₃ = 3.ⁿ C₂ (n + 1)!/(n + 1 - 3)! × 3! = (3)× (n)!/ (n - 2)! × 2! ⇒ (n + 1) × (n)!/(n - 2)! ×3 ×2! = 3 × (n)!/(n-2)! × 2! ⇒ n + 1/3 = 3 ⇒ n + 1 = 9 ⇒ n = 8 Class 11th NCERT.

Choice (d) is correct.
Given, ⁿ ⁺ ¹C₃ = 3.ⁿ C₂
(n + 1)!/(n + 1 – 3)! × 3! = (3)× (n)!/ (n – 2)! × 2! ⇒ (n + 1) × (n)!/(n – 2)! ×3 ×2! = 3 × (n)!/(n-2)! × 2!
⇒ n + 1/3 = 3 ⇒ n + 1 = 9 ⇒ n = 8
