Read the given information carefully and answer the questions.
Each of the six sections, U, V, W, X, Y and Z of the same class has different number of students. Only Z has more number of students than X. V has more number of students than Y but less than U. W has more number of students than both Y and U. The section having the third highest number of students has 39 students. Y has 24 students.
If the number of students in sections W + Z is sixty six more than the number of students in section Y, how many of students are there in section Z ?
Only Z has more number of students than X, => Z has the highest number of students and X has second highest.
V has more number of students than Y but less than U, => U > V > Y
W has more number of students than both Y and U, => W > U > V > Y
Combining above statements, we get
$$\therefore$$ Z > X > W > U > V > Y
Number of students in W = 39 and Y = 24
Let number of students in section Z = $$z$$
=> $$39 + z = 24 + 66$$
=> $$z = 90 - 39 = 51$$
=> Ans - (C)
