AP EAMCET · Maths · Binomial Theorem
The least value of \(n\) such that \({ }^{(n-1)} C_6+{ }^{(n-1)} C_7 < { }^n C_8\) is
- A 14
- B 15
- C 16
- D 117
Answer & Solution
Correct Answer
(C) 16
Step-by-step Solution
Detailed explanation
\({ }^{(n-1)} C_6+{ }^{(n-1)} C_7 15\) \(\therefore \quad\) The least \(n\) satisfying above condition is \(n=16\).
