(d) Number of students who speak only English = (Number of students who speak English – Number of students who speak both Hindi and English)

= 21 – 10 = 11

Number of students who speak Hindi = (Total no of students – No of students who speak only English)

= 50 – 11 = 39

∴Number of students who speak only Hindi = (Number of Hindi speaking students – no of students

who speak both languages) = 39 – 10 = 29
