    டெஸ்ட் பேட்ச் மட்டும் join பண்ணி, 2 month's ல பாதிக்கு பாதின்ற போல எல்லாத்தையும் ஒரு அளவுக்கு படிச்சு 29 டெஸ்ட் ல, 24 டெஸ்ட் அட்டென்ட் பண்ணி, இன்னைக்கு எக்ஸாம் போனேன். நான் Maths தவிர்த்து மீதி எல்லாத்தையும் கொஞ்சம் நல்லாவே படிச்சேன். ஏன்னா எனக்கு Maths பாக்க டைம் கொஞ்சம் கூட இல்லை 😢. இது தான் முதல் முறை, Tnpsc group 2 Attent பண்றது. அதுவும் புக்ஸ் லாம் மாறிடுச்சு னு கூட தெரியாம தான் டெஸ்ட் பேட்ச் join பண்ணேன். So, இந்த டைம் நான் மார்க் விட்டுருக்கலாம். ஆனால் அடுத்த எக்ஸாம் ல கண்டிப்பா Maths 25/23 நாச்சும் மார்க் வாங்குவேன்.. அதேபோலவே Tnpsc ல பாஸ் ஆகி நிச்சயம் வேலைக்கும் போவேன் 🎉🎉

    Hi sir , question no 73. If B is 20% efficient than A then ratio is 100:80 then it’s 5:4 . Now if we calculate 5x = 15/2 ; x = 3/2 . Then calculating for B = 4x = 4 * 3/2 = 6 hours. Answer is C for question number 73.

    • @Jofrajeeva
      @Jofrajeeva 2 месяца назад +1

      Same question you can calculate in simple way. 20% of 7.5 = 1.5. Just reduce this 1.5 from 7.5 , you get 6 hours

      @@Jofrajeeva I understand time and efficiency are inversely proportional
      My doubt is A vida B 20% more efficient
      So neenga 80:100 nu edutheengala?
      When A = 80, B = 120/100 × 80 =96 dha varudhu
      Ratio should be 80:96 (coz base value is A)
      For example,
      B is 20% more than A → "does not mean" A is 20% less than B
      Lets see this ratio,
      B:A = 120:100 → B vandhu A vida 20% more, A vandhu B vida 16.66% less
      100/120 × 100 = 83.33%
      So edha base value'vaa vaikuromo adhula irundhu dhananga % add or subtract pananum😅
