Detailed Solution
Download Solution PDFदिलेले आहे:
वस्तूच्या किमतीत सलग 15% आणि 20% वाढ झाली
नंतर 10% आणि 5% कमी झाली
गणना:
समजा, वस्तूची किंमत 100 मानू.
⇒ 115/100 × 120/100 × 90/100 × 95/100 = 117990000/100000000
⇒ 11799/10000
निव्वळ टक्केवारी बदल = 11799 - 10000/10000 × 100 = 1799/100 = 17.99
⇒ 18%
∴ योग्य उत्तर 18% जास्त आहे.
