वर्गातील 43 विद्यार्थ्यांपैकी 13 जणांनी स्पॅनिश आणि पोर्तुगीज या दोन्ही भाषा शिकण्यासाठी नावे नोंदवली आहेत. 21 विद्यार्थ्यांनी पोर्तुगीज भाषेसाठी नावे नोंदवली आहेत. जर वर्गात नावे नोंदवलेल्या विद्यार्थ्यांपैकी दोनपैकी किमान एक भाषा शिकण्यासाठी नाव नोंदवले असेल तर फक्त स्पॅनिश भाषा शिकण्यासाठी, पण पोर्तुगीजसाठी नाही अशा विद्यार्थ्यांची संख्या दर्शवणारा पर्याय निवडा. In a class of 43 students, 13 enrolled for both Spanish and Portuguese. 21 enrolled for Portuguese. If the students of the class enrolled for at least one of the two subjects, then select the option that indicates the number of students who enrolled only for Spanish and not Portuguese.
Total students = 43, Portuguese = 21, Both = 13. Only Portuguese = 21 - 13 = 8. Since everyone took at least one subject, Only Spanish = Total - Only Portuguese - Both = 43 - 8 - 13 = 22.
