Of the five boys A, B, C, D and E two are good, one is poor and two are average is studies. Two of them study in post-graduate classes and there in under-graduate classes. One comes from a rich family, two from middle-class families and two from poor families. One of them is interested in music, two in acting and one in sports. Of those studying in under-graduate classes, two are average and one is poor in studies. Of the two boys interested in acting, one is a post-graduate student. The one interested in music comes from a middle-class family. Both the boys interested in acting are not industrious. The two boys coming from middle-class families are average in studies and one of them is interested in acting. The boy interested in sports comes from a poor family, while the one interested in music is industrious. E is industrious, good in studies, comes from a poor family and is not interested in acting, music or sports. C is poor in studies inspite of being industrious. A comes from a rich family and is not industrious but good in studies. B is industrious and comes from a middle-class family.
Name the boy who is not industrious and is average in studies.
(I). A and E are good in studies; C is poor in studies. The remaining two i.e. B and D are average in studies.
(II). A comes from a rich family; E belong to a poor family.
Now, B and D are average in studies. So, B and D come from middle-class families.
Now, C remains. So, C belongs to a poor family (because two boys come from poor families).
(III). The students who are poor and average in studies are in under-graduate classes i.e. B, C and D.
The remaining two i.e. A and E study in post-graduate classes.
(IV). B, C and E are industrious. A is not industrious. Now, two boys are not industrious.
So, D is also not industrious.
(V). Two boys interested in acting are not industrious. So, A and D are interested in acting. The boy interested in music comes from middle-class family. B and D come from middle-class families. But D is interested in acting. So, B is interested in music. E is not interested in any activity. Clearly, C is interested in sports.
D is not industrious and is average in studies.
