एक पेड़ पर प्रतिदिन फल तोड़े गए: \(12,18,24,\ldots\)। पहले (15) दिनों में कुल कितने फल तोड़े गए?

Fruits plucked from a tree each day were \(12,18,24,\ldots\). How many fruits were plucked in the first (15) days?

Explanation opens after your attempt
Correct Answer

C. (810)

Step 1

Concept

The fifteenth term is (96), so the total is (S_{15}=\frac{15}{2}(12+96)=810) fruits. Treat the number of days as the number of terms.

Step 2

Why this answer is correct

The correct answer is C. (810). The fifteenth term is (96), so the total is (S_{15}=\frac{15}{2}(12+96)=810) fruits. Treat the number of days as the number of terms.

Step 3

Exam Tip

पंद्रहवाँ पद (96) है, इसलिए कुल (S_{15}=\frac{15}{2}(12+96)=810) फल हैं। दिनों की संख्या को पदों की संख्या मानें।
