Directions: Study the following information carefully and answer the questions given below:
Eight persons work in two different departments i.e., Research and Agriculture and all of them get different marks in the Research and Agriculture sessions organized by organization. Each of them has different years of experience (in whole number) in their departments. They have qualification in either HR or diploma. No one has more experience than 11 years. Equal number of persons work in both departments. A and D have same qualification. B gets twice marks as the experience of F and doesn’t qualification in HR. F has twice experience than E who has more experience than A. F did Diploma same as C. A’s marks is two more than B’s marks but not multiple of 7. C and D have different qualification. The one who gets marks in multiple of 8 works in agriculture department. G’s experience is equivalent to smallest two digits prime number. F have 4 marks less than E. G’s experience and C’s Mark are not equal. G gets the marks which is 3/2 of the marks get by A. C’s experience is five times of A’s experience. The marks get by D is twice of C’s experience. A and D work in the same department but not as B. A gets marks which is twice of C marks. C and F work in same department but not as A’s department. A has even number of experiences. B has more experience than H but less than D and all have prime number experience. E and H work in same department. E, G and H have same qualification but different than B. H marks is 9 more than E and just less than D.
Which among the following statement is not true?
- A.
G has maximum years of experience among all
- B.
Only three persons are qualified in Diploma
- C.
A gets the fourth highest marks
- D.
More than three persons have more experience than D
- E.
None is true
Show answer & explanation
Correct answer: D
Concept
In a linear-data puzzle, fix every quantity from the clue that gives a single forced value, then propagate. A clue of the form "X = k times Y" plus a hard ceiling (here, no experience exceeds 11) usually pins one variable to exactly one whole number; once an anchor is fixed, the remaining values follow by substitution and by the distinctness of every assignment.
Application: fixing experience
G's experience equals the smallest two-digit prime, so G = 11.
C's experience is five times A's, and A is even with the maximum capped at 11; A = 2 forces C = 10 (A = 4 would give C = 20, which exceeds 11).
F is twice E and E is greater than A (2). Among the remaining whole numbers this forces E = 4, F = 8 (E = 3 would make F = 6, but then no consistent set of three distinct primes is left for B, H, D).
B, H, D each take a prime value with H less than B less than D. The primes still unused are 3, 5, 7, so H = 3, B = 5, D = 7.
Experience is therefore: A = 2, B = 5, C = 10, D = 7, E = 4, F = 8, G = 11, H = 3.
Application: fixing marks
B's marks are twice F's experience (8), so B = 16.
A's marks are two more than B's, so A = 18 (18 is not a multiple of 7, as required).
A's marks are twice C's, so C = 9.
G's marks are 3/2 of A's, so G = 27.
D's marks are twice C's experience (10), so D = 20.
H is 9 more than E and sits just below D (20); E = 10 gives H = 19 and F = E - 4 = 6, leaving every value distinct.
The completed grid
Person | Experience | Marks |
|---|---|---|
A | 2 | 18 |
B | 5 | 16 |
C | 10 | 9 |
D | 7 | 20 |
E | 4 | 10 |
F | 8 | 6 |
G | 11 | 27 |
H | 3 | 19 |
Cross-check the asked statement
The question asks which statement is NOT true. D has 7 years of experience. Counting everyone with strictly more experience than D: G (11), C (10) and F (8) — exactly three people. The claim that more than three (i.e. four or more) have greater experience than D is contradicted by the grid, so that statement is the false one.
The remaining statements each hold: G's 11 years is the largest, exactly three people (B, C, F) hold a Diploma, and A's 18 marks rank fourth highest (after 27, 20 and 19).
