Detailed Solution
Download Solution PDFदिलेले:
साखरेच्या किमतीत % वाढ = 25%
वापरलेले सूत्र:
खर्च = किंमत × प्रमाण
गणना:
समजा साखरेवर सुरुवातीचा खर्च 100 रुपये होता
आता, किंमत 30% वाढली
नवीन किंमत = (100 + 100 × 30%) = 130
खर्चात बदल न करता रु.130 वरून रु.30 कमी करावे लागतील.
⇒ 130 - 30 = 100
∴ वापरातील घट = 30/130 × 100=\(23\frac{1}{13}\%\)
Shortcut Trick
100 → + 30% → 130 _____ - Y% → 100
आता, Y = 30/130 × 100 = \(23\frac{1}{13}\%\)
