15. Next number in the series 4,6,9,13,……is
- 15
- 12
- 18
- 17
Answer and Explanation
Answer: (3) 18
Explanation:
-> The pattern is that the difference is increasing by 1 each time starting with 2.
-> Next difference should be +5. So, 13 + 5 = 18
16. Next number in the series 3,6,8,16,18,……is
- 28
- 36
- 54
- 34
Answer and Explanation
Answer: (2) 36
Explanation:
-> Series follows alternates between two patterns:
● Pattern 1: Multiply by 2
● Pattern 2: Add 2
-> Hence: 3 × 2 = 6, 6 + 2 = 8, 8 × 2 = 16, 16 + 2 = 18, thus 18 x 2 = 36
17. If the sum of two number is 32 and their difference is 16, the smaller number would be
- 6
- 8
- 16
- 18
Answer and Explanation
Answer: (2) 8
Explanation:
-> Let’s call the smaller number x and the larger number y.
-> Given: x + y = 32 (y = 32 -x) and y – x = 16
-> Substituting this into the second equation:
(32 – x) – x = 16
32 – 2x = 16
-2x = -16
-> x = 8

25. According to the Simon New Comb Theory:-
- The probability of concurrence of all the events is equal to the continued product of the probability of each event
- The probability of concurrence of all the events is equal to the sum of the probability of each event
- The probability of concurrence of all the events is equal to the continued product of the probability and divided by probability of single event
- The probability of concurrence of all the events is equal to the four times of the probability of single event
Answer and Explanation
Answer: (1) The probability of concurrence of all the events is equal to the continued product of the probability of each event
Explanation:
-> Newcomb’s Theory states that the probability of concurrence of all events is equal to the product of the probabilities of the individual events.
-> It is named after Professor Simon Newcomb.
-> This rule is usually cited in the process of individualization where scientific examiners have to use probability.
-> In two data events that are independent is commonly defined as the Multiplication Rule of Probability
-> Formula: P(A and B and C…) = P(A) × P(B) × P(C) × …
Where,
● P(A and B and C…) is the probability of all events occurring together
● P(A), P(B), P(C), etc. are the individual probabilities of each event
-> Example:
● Given: A document typed on an old-fashioned typewriter is analyzed and the typewriter has 42 type bars and 84 characters.
● Individual Characteristics: The document shows five individual characteristics:
(a) One caused by a misaligned type bar (probability = 1/42).
(b) Four others caused by defects in individual characters (probability = 1/84 each).
● Now as per Simon Newcomb’s Probability Calculation:
The probability for these five characteristics happening together is:
=> 1/42 x 1/84 x 1/84 x 1/84 x 1/84 = 1/ 2,091,059,712
=> This result is a figure greater than the total number of typewriters of that particular model in existence.
