एक मशीन का मूल्य (V(y)=c-2200y) है। यदि (V(4)=31200), तो (V(9)) क्या होगा?
A machine's value is (V(y)=c-2200y). If (V(4)=31200), what will (V(9)) be?
Explanation opens after your attempt
B. (20200)
Concept
From (c-8800=31200), (c=40000). (V(9)=40000-19800=20200).
Why this answer is correct
The correct answer is B. (20200). From (c-8800=31200), (c=40000). (V(9)=40000-19800=20200).
Exam Tip
(c-8800=31200) से (c=40000) है। (V(9)=40000-19800=20200) है।
