Correct answer

Answer: (b)B.

Four

Why this answer is correct

From the given instructions:

  1. X is heavier than Q. Q is heavier than P. P is heavier than only three people. So, we have two cases;

Case 1:

X/ > X/ > Q > P > __ > __ > __

Case 2:

X > Q > __ > P > __ > __ > __

  1. T is heavier than S but lighter than R. U is heavier than R but lighter than Q. So, Case 1 is invalid.

So, Final Arrangement,

X > Q > U > P > R > T > S

Hence, four boys are lighter than U.
