Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFकुल छात्र = 640
लड़कों से लड़कियों का अनुपात = 5 : 3
लड़कों की संख्या = [5/8] × 640 = 400
लड़कियों की संख्या = 640 - 400 = 240
मान लीजिए विद्यालय में x लड़कों ने प्रवेश लिया।
प्रश्नानुसार
(400 + x)/(240 + 30) = 14/9
⇒ 400 + x = [14/9] × 270
⇒ x = 420 - 400
⇒ x = 20
∴ विद्यालय में 20 छात्रों ने प्रवेश लिया।Last updated on Jun 25, 2025
