Show answer & explanation
Correct answer: D
Only G has an exam before X, so G is on Monday and X is on Tuesday. Since W and X have three people between them, W is on Saturday. I and F also have three people between them; with F after X and E before F but after Y, the valid order is: Monday G, Tuesday X, Wednesday I, Thursday Y, Friday E, Saturday W, Sunday F. Therefore four people have exams after I.
