यदि \(^{10}C_4=^{10}C_m\) और \(m\neq4\) है तो (m) क्या होगा?
If \(^{10}C_4=^{10}C_m\) and \(m\neq4\) what is (m)?
Explanation opens after your attempt
B. (6)
Concept
By the complementary identity (m=10-4=6). In exams apply \(^{n}C_r=^{n}C_{n-r}\) quickly.
Why this answer is correct
The correct answer is B. (6). By the complementary identity (m=10-4=6). In exams apply \(^{n}C_r=^{n}C_{n-r}\) quickly.
Exam Tip
पूरक पहचान से (m=10-4=6) होगा। परीक्षा में \(^{n}C_r=^{n}C_{n-r}\) तुरंत लगाएँ।
