यदि \(^{n}C_{3}=4,^{n}C_{2}\) है, तो (n) का मान क्या है?
If \(^{n}C_{3}=4,^{n}C_{2}\), what is the value of (n)?
Explanation opens after your attempt
B. (14)
Concept
The ratio is \(\frac{^{n}C_{3}}{^{n}C_{2}}=\frac{n-2}{3}\), so (n=14). In exams write the ratio first.
Why this answer is correct
The correct answer is B. (14). The ratio is \(\frac{^{n}C_{3}}{^{n}C_{2}}=\frac{n-2}{3}\), so (n=14). In exams write the ratio first.
Exam Tip
अनुपात \(\frac{^{n}C_{3}}{^{n}C_{2}}=\frac{n-2}{3}\) होगा, इसलिए (n=14)। परीक्षा में पहले अनुपात लिखें।
