RRB Group D Mock Test - 37 - Question 26

If DRY is coded as 1800 and BAT is coded as 40, the code of which of the following words is 200?

Detailed Solution for RRB Group D Mock Test - 37 - Question 26

The code for a word is the product of the position of the letters of the word in the alphabetical series.

DRY - 4*18*25 = 1800
BAT - 2*1*20 = 40

Let us evaluate the options using the same logic.

GATE - 7*1*20*5 = 700
DEBT - 4*5*2*20 - 800
BEED - 2*5*5*4 - 200
DATE - 4*1*20*5 - 400
Therefore, option C is the right answer.

RRB Group D Mock Test - 37 - Question 27

If ‘+’ means ‘-’, ‘-’ means ‘*’, ‘*’ means ‘/’ and ‘/’ means ‘+’, then what is the value of the following expression?
13 - 13 / 3 - 63 * 9 + 2 -5

Detailed Solution for RRB Group D Mock Test - 37 - Question 27

Let us replace the symbols with the actual operators.

13 - 13 / 3 - 63 * 9 + 2 -5 = 13 * 13 + 3*63/9 - 2*5

Applying BODMAS rule, we get, 169 + 3*7 - 10 = 180
Therefore, option B is the right answer.

RRB Group D Mock Test - 37 - Question 28

Which of the following options should come in the place of x,y and z in that order in the grid if it is known that all the numbers from 1 to 9 are used exactly once and the sums of the elements along both the diagonals are equal to the sum of the elements of the first column? Detailed Solution for RRB Group D Mock Test - 37 - Question 28

Each number is used only once and the sums of numbers along both the diagonals are equal.
6 + z + y = 2 + 8 + z
=>y = 4
6 + 1+ 8 = 6 + z + 4
=> z = 5 and x = 3.
(x,y,z) = (3,4,5).
Therefore, option A is the right answer.

RRB Group D Mock Test - 37 - Question 29

Consider the given statements to be true even if they are at odds with generally known things. Based on the statement, evaluate which of the conclusions follow:

II: All trees being shrubs is a possibility.

Detailed Solution for RRB Group D Mock Test - 37 - Question 29

The given statements can be expressed diagrammatically as follows without violating any of the conditions. Shrubs that are herbs cannot be trees as no herb is a tree. Therefore, conclusion I does not follow.
Trees and herbs can be 2 disjoint subsets of Shrubs. Therefore, conclusion II follows.

Only conclusion II follows. Therefore, option B is the right answer.

Goat is a prey. Goats are herbivores and hence, they can be purely termed as preys. Tiger is an apex predator.

Therefore, the Venn diagram must contain 2 large intersecting circles and 3 small circles, one in each of the regions formed by the intersecting circles. Only option C satisfies this condition. Hence, option C is the right answer.

Ganesh walks 20 m towards the East. Then, he walks 3 m towards the south. He takes a turn and walks 4 m towards the East. Finally, he walks 10 m towards the North and comes to a halt. How far is Ganesh from his starting point?

Detailed Solution for RRB Group D Mock Test - 37 - Question 37

The given statements can be expressed diagrammatically as follows: Total distance travelled towards the East = 20 + 420+4 = 2424 m.
Total distance travelled towards the North = -3 + 10−3+10 = 77 m.
Distance from the starting point can be found using the Pythagoras theorem. RRB Group D Mock Test - 37 - Question 38

5 persons A, B, C, D and E live on 5 different floors of a building. The floors are numbered from 1 to 5, 1 being the topmost floor and 5 being the bottom most floor.

E lives on a floor above B. Who lives on floor 2?

Detailed Solution for RRB Group D Mock Test - 37 - Question 38

1 is the topmost floor and 5 is the bottom-most floor. A lives on an odd numbered floor above D. Therefore, A must be living on floor 1 or 3. D has more persons living above him than below him. Therefore, D must be living on floor 4 or 5. D lives on an even numbered floor. Therefore, D must be living on floor 4. C lives on an odd numbered floor above D but below A. Therefore, A must be living on floor 1 and C must be living on floor 3. E lives on a floor above B. Therefore, B must be living on floor 5 and E must be living on floor 2.

The final arrangement is as follows:

1 - A
2 - E
3 - C
4 - D
5 - B

As we can see, E lives on the second floor. Therefore, option B is the right answer.
