also,
from class b students who passed in first class = = 

therefore, from above results it is clear that in the both the classes equal fraction of students passed in the first class
a, b and c a, b & c a

a
c, i think 2 a - ii, b - iv, c - i, d - iii tan a/2 is equal to the first one. ha = 2hl 1 a c d
2 a
3 c
4 b
5 c
i got a 100% answer: `1/221`
solution: n/a
