Study Notes
अर्थमैटिक की भूमिका
- अर्थमैटिक के अंतर्गत अंकगणित का अध्ययन किया जाता है, जो परीक्षा में महत्वपूर्ण है।
- वर्तमान समय में, विशेषकर सीज़न के दौरान, अर्थमैटिक से जुड़े 24 से 25 प्रश्न पूछे जाते हैं।
- एवरेज और डिस्टेंस जैसे महत्वपूर्ण विषयों पर केंद्रित रहने की जरूरत है।
कक्षा में आंकड़ों का महत्व
- कक्षा में 50 छात्रों के अंक का औसत 12 मार्क्स है, जिससे कक्षा की शैक्षणिक स्थिति का पता चलता है।
- किसी एक विद्यार्थी के औसत अंक को समझने के लिए, कक्षा की प्रदर्शन स्तर को जानना जरूरी है।
औसत का सूत्र
- औसत निकालने के लिए सूत्र: आंकड़ों का योग ÷ आंकड़ों की संख्या।
- औसत से यह निश्चित होता है कि सभी छात्रों के प्रदर्शन का एक समान माप तैयार होता है।
महत्वपूर्ण बातें
- परीक्षा में अर्थमैटिक से प्रश्नों की महत्ता को नजरअंदाज नहीं करना चाहिए।
- कठिन विषयों का सरलता से अध्ययन करने के लिए सही दृष्टिकोण अपनाना आवश्यक है।
