answer: Stream of consciousness: We need a number that is a multiple of 7 that will give a remainder of 1 when divided by 2, 3, 4, 5, and 6. The least common multiple of these numbers is 60. So, we need a multiple of 7 that is 1 greater than a multiple of 60. The answer is (B).

q: Find the third proportional to 4 and 16?
Options:
(A) 80
(B) 12
(C) 64
(D) 78
(E) 72
a: Stream of consciousness: Formula = Third proportional = (b b)/a
A = 4 and B = 16
(16 16)/ 4 = 256/4 = 64 The answer is (C).

question: Find the average of the first 41 natural numbers?
Options:
(A) 8
(B) 9
(C) 10
(D) 11
(E) 21
answer: Stream of consciousness: Average of the first 'n' natural numbers = (n + 1)/2
We get (41 + 1)/2 = 21 The answer is (E).

q: A light has a rating of 60 watts, it is replaced with a new light that has 12% higher wattage. How many watts does the new light have?
Options:
(A) 105
(B) 67
(C) 80
(D) 60
(E) 100
a: Stream of consciousness: Final number = Initial number + 12%(original number) = 60 + 12%(60) = 60 + 7 = 67 The answer is (B).

question: 3 candidates in an election and received 1136, 7636 and 11628 votes respectively. What % of the total votes did the winningcandidate got in that election?
Options:
(A) 30%
(B) 59%
(C) 57%
(D) 64%
(E) 69%
answer: Stream of consciousness: Total number of votes polled = (1136 + 7636 + 11628) = 20400
So, Required percentage = 11628/20400 * 100 = 57% The answer is (C).

question: If a man can cover 12 metres in one second, how many kilometres can he cover in 3 hours 45 minutes?
Options:
(A) 288
(B) 162
(C) 878
(D) 168
(E) 122
answer:
Stream of consciousness: 12 m/s = 12 * 18/5 kmph
3 hours 45 minutes = 3 3/4 hours = 15/4 hours
Distance = speed * time = 12 * 18/5 * 15/4 km = 162 km. The answer is (B).
