किसी समांतर श्रेढ़ी में \(S_{12}=540\) और \(S_{24}=1944\) है। \(S_{36}\) का मान ज्ञात कीजिए।

In an AP, \(S_{12}=540\) and \(S_{24}=1944\). Find the value of \(S_{36}\).

Explanation opens after your attempt
Correct Answer

C. (4212)

Step 1

Concept

The given sums give (a=12) and (d=6), so \(S_{36}=4212\). From two partial sums, determine the AP first.

Step 2

Why this answer is correct

The correct answer is C. (4212). The given sums give (a=12) and (d=6), so \(S_{36}=4212\). From two partial sums, determine the AP first.

Step 3

Exam Tip

दिए गए योगों से (a=12) और (d=6) मिलते हैं, इसलिए \(S_{36}=4212\) है। दो आंशिक योगों से पहले AP निर्धारित करें।

एक आयत की लंबाई चौड़ाई से (15) मीटर अधिक है। लंबाई (6) मीटर और चौड़ाई (5) मीटर बढ़ाने पर नया क्षेत्रफल (1944) वर्ग मीटर होता है। मूल चौड़ाई क्या है?

A rectangle has length (15) m more than its breadth. When length is increased by (6) m and breadth by (5) m, the new area is (1944) square m. What is the original breadth?

Step 2

Why this answer is correct

The correct answer is C. (39) मीटर / (39) m. If original breadth is (x), the new area is ((x+21)(x+5)=1944). This gives (x=39).

Step 3

Exam Tip

मूल चौड़ाई (x) हो तो नया क्षेत्रफल ((x+21)(x+5)=1944) है। इससे (x=39) मिलता है।
