Detailed Solution
Download Solution PDFदिलेले आहे:
पहिल्या वर्षात शाळेची पटसंख्या 12% ने वाढली
दुसर्‍या वर्षी 12% कमी होते आणि तिसर्या वर्षी 10% ने वाढते.
तिसर्या वर्षाच्या शेवटी पटसंख्या जवळपास 10842 आहे.
गणना:
सुरुवातीची पटसंख्या x समजूया.
1 ल्या वर्षानंतर, पटसंख्या
⇒ x × (1 + 12/100) = x × 1.12
2 र्‍या वर्षानंतर, पटसंख्या
⇒ x × 1.12 × (1 - 12/100) = x × 1.12 × 0.88
3 र्‍या वर्षानंतर, पटसंख्या,
⇒ x × 1.12 × 0.88 × (1 + 10/100)
⇒ x × 1.12 × 0.88 × 1.10
आपल्याला माहित आहे की 3 र्‍या वर्षानंतर, पटसंख्या 10842 आहे.
⇒ x × 1.12 × 0.88 × 1.10 = 10842
⇒ x = 10842 / (1.12 × 0.88 × 1.10)
⇒ x = 10842 / 1.08384
⇒ x ≈ 10000
∴ पहिल्या वर्षाच्या सुरुवातीला शाळेची पटसंख्या जवळपास 10000 होती.
