Draw a table with Student, Collage (Institute) and Subject.
R studies in the same college as P, who studies MBA in college B.
T studies BCA in college A and his brother W studies Aviation Technology in college C.
S studies Journalism in the same college as Q.
Neither R nor Z studies BCA.
The girl who studies BCA does not study in college C.
No girl studies Journalism or MBA.
Two of the seven students study BCA, two study medicine and one each studies Aviation Technology, Journalism and MBA.
Assume + sign is for Boys and - sign is for girls.
Based on the above information, The classification of the group is as follow in the table.

GRAPE = 2 7 3 5 4
FOUR = 1 6 8 7
So, G = 2, R = 7, A = 3, P = 5, E = 4,
F = 1, O = 6, U = 8,
R = 7
GROUP = 2 7 6 8 5

7^th letter from right = (27 - 7) th = 20^th letter from left = K

According to given question,
R = s
A = u
P = m
M = l
S = a
O = d
Replace the each capital from given relationship for M A P S R O, We will get
M → l
A → u
P → m
S → a
R → s
O → d

1st term = 95
2nd term = 95 + 20.5 = 115.5
3rd term = 115.5 + 22.5 = 138
4th term = 138 + 24.5 = 162.5
5th term = 162.5 + 26.5 = 189

Thus, the missing term is 4th term = 162.5
