Reasoning: 1/2 * 10 * 5 = 25 m2
Ans: (B)
Question: The area of a triangle is with base 10m and height 5m?
Options:
(A) 11
(B) 25
(C) 787
(D) 122
(E) 12

Rationale: Ordering the data from least to greatest, we get:
87, 88, 88, 90, 92, 93, 95, 96, 98
The median score is 92.
The answer: (C)
Question: What is the median from the below series
90, 92, 93, 88, 95, 88, 97, 87, and 98
Options:
(A) 85
(B) 89
(C) 92
(D) 98
(E) 100

Reasoning: Each of the numbers is odd number except 22. The number 22 is the only even number.
Ans: (C)
Question: Find the odd man out? 3, 7, 15, 17, 22, 27, 29
Options:
(A) 15
(B) 17
(C) 22
(D) 27
(E) 0

Rationale: Part filled by (A + B + C) in 3 minutes = 3(1/30 + 1/20 + 1/10) = 11/20
Part filled by C in 3 minutes = 3/10
Required ratio = 3/10 * 20/11 = 6/11
The answer: (B)
Question: Three pipes A, B and C can fill a tank from empty to full in 30 minutes, 20 minutes and 10 minutes respectively. When the tank is empty, all the three pipes are opened. A, B and C discharge chemical solutions P, Q and R respectively. What is the proportion of solution R in the liquid in the tank after 3 minutes?
Options:
(A) 6/17
(B) 6/11
(C) 6/18
(D) 6/19
(E) 6/10

Reasoning: Speed = 60 * 5/18 = 50/3 m/sec
Length of the train = speed * time = 50/3 * 3 = 50 m
Ans: (D)
Question: A train running at the speed of 60 km/hr crosses a pole in 3 sec. What is the length of the train?
Options:
(A) 85 m
(B) 70 m
(C) 115 m
(D) 50 m
(E) 150 m

Reasoning: Maximum points of intersection between n different circles = n*(n - 1) = 20*19 = 380
Ans: (A)

Question: There are different 20 circles. What is the number of the greatest possible points with which the circles intersect?
Options:
(A) 380
(B) 200
(C) 110
