[Ans] (A)
[Question] In an office, 60 percent of the workers have at least 5 years of service, and a total of 16 workers have at least 10 years of service. If 90 percent of the workers have fewer than 10 years of service, how many of the workers have at least 5 but fewer than 10 years of service?
Options:
(A) 96
(B) 64
(C) 50
(D) 144
(E) 160
[CoT] (10/100)Workers = 16 = > number of workers = 160
(60/100)*Workers = x+16 = > x = 96

[Ans] (C)
[Question] In Hockey game, one player throws two fair, six-sided die at the same time. If the player receives at least a five or a one on either die, that player wins. What is the probability that a player wins after playing the game once?
Options:
(A) 1/3
(B) 4/9
(C) 5/9
(D) 2/3
(E) 3/4
[CoT] In Hockey game, Probably the easiest approach would be to find the probability of the opposite event and subtract it from 1:
P(win) = 1- P(not win) = 1 - 4/6*4/6 = 5/9.

[Ans] (B)
[Question]
The speed of a boat in still water is 60kmph and the speed of the current is 10kmph. Find the speed downstream and upstream?
Options:
(A) 40, 68 kmph
(B) 70, 50 kmph
(C) 90, 60 kmph
(D) 40, 60 kmph
(E) 20, 60 kmph
[CoT] Speed downstream = 60 + 10 = 70 kmph
Speed upstream = 60 - 10 = 50 kmph
