In a donation campaign (200) rupees are received on the first day and (100) rupees more each next day. How many days will it take to collect (5400) rupees?
Explanation opens after your attempt
Correct Answer
B. (9)
Step 1
Concept
The donation amounts are \(200,300,400,\ldots\) and \(S_n=5400\) gives (n=9). Exam tip: form an \(S_n\) equation for the target total.
Step 2
Why this answer is correct
The correct answer is B. (9). The donation amounts are \(200,300,400,\ldots\) and \(S_n=5400\) gives (n=9). Exam tip: form an \(S_n\) equation for the target total.
Step 3
Exam Tip
दान राशि \(200,300,400,\ldots\) है और \(S_n=5400\) से (n=9)। परीक्षा में लक्ष्य कुल राशि के लिए \(S_n\) का समीकरण बनाएं।
