यदि (p(x)=\frac{x}{7}+a) और (p(21)=16), तो (a) का मान क्या है?
If (p(x)=\frac{x}{7}+a) and (p(21)=16), what is the value of (a)?
Explanation opens after your attempt
C. (13)
Concept
From (p(21)=3+a=16), we get (a=13). In fractional form, substitute the value of (x) first.
Why this answer is correct
The correct answer is C. (13). From (p(21)=3+a=16), we get (a=13). In fractional form, substitute the value of (x) first.
Exam Tip
(p(21)=3+a=16) से (a=13) मिलता है। भिन्न रूप में पहले (x) का मान रखें।
