Detailed Solution
Download Solution PDFगणना :
शाळेतील जीवशास्त्र निवडलेल्या महिला विद्यार्थ्यांची संख्या B = 400 × 36% × 7/(7 + 5) = 84
शाळेत जीवशास्त्र निवडलेल्या महिला विद्यार्थ्यांची संख्या D = 800 × 18% × 9/(3 + 9) = 108
आता, गुणोत्तर = 84 : 108 = 7 : 9
∴ शाळा B आणि शाळा D मध्ये जीवशास्त्र निवडलेल्या महिला विद्यार्थ्यांच्या संख्येचे गुणोत्तर 7 : 9 आहे.
