BITSAT Logical Reasoning Test - 7 - Question 3

In the given question, find out which of the answer figures (1), (2), (3) and (4) completes the figure matrix.

Detailed Solution for BITSAT Logical Reasoning Test - 7 - Question 3

Figure in first column is removed from the figure in second column and then the colour filled in the remaining shape is removed to get the figure in column 3.

In the first row, there is a circle in first column and both circle and triangle in second column. To obtain the figure in third column, figure in first column is subtracted from figure in second column, i.e circle is reduced from second column figure and only triangle is left, which is filled with black colour. Removing that black colour we get a hollow triangle.

Similarly in row 3, rectangle and circle if reduced from figure in second column and only cross is left, which is filled with black colour. So, figure in third column will be a hollow cross.

Hence, option 1 is correct.

A man said to a lady, 'Your mother's husband's sister is my aunt".
The lady’s mother’s husband which means he is the father of that lady. Lady’s father’s sister will be an aunt to that lady. And his father's sister is aunt to the man also. This means, lady's father is father of the man also. So, the lady and the man are siblings having same parents.

The code can be drawn into the family tree as:


It can be concluded that:
T # L means T is the wife of L.
L $ M means L is the father of M.
M $ P means M is the father of P.
P 1 J means P is the son of J. 
J Δ N means J is the mother of N. So, M and J are parents of P and N. 
N n K means N is the husband of K.
According to the given information, T, J, K are females and L, M, P and N are males. Thus, there are three females and four males. So, statement in option A is correct.
And also, statement in option B is correct.
Since, N is the husband of K, then K has to be a female. So, statement in option C is incorrect.
Thus, option C is the correct answer.

BITSAT Logical Reasoning Test - 7 - Question 16

Directions: Read the given information carefully and answer the questions given below:
Vikram started from point R and walked straight 7 km west, then turned left and walked 2 km and again turned left and walked straight 4 km. In which direction is he from R?

Detailed Solution for BITSAT Logical Reasoning Test - 7 - Question 16

According to the given information, the following direction diagram can be made,

From the above diagram, with reference to point R, point U is located in the South-West.
Hence, this is the correct answer.

BITSAT Logical Reasoning Test - 7 - Question 17

Directions: Read the given information carefully and answer the questions given below:
Vidya walks 14 m towards West, then turns to her right and walks 14 m and then turns to her left and walks 10 m. Again turning to her left, she walks 14 m.

What is the shortest distance (in m) between her starting point and the present position?

Detailed Solution for BITSAT Logical Reasoning Test - 7 - Question 17

Let Vidya starts from the point A, we will use the information given in the problem and draw the Vidya’s movement as shown below:

From the diagram, we can conclude that,
EB = CD = 10 m
Final point where Vidya ends his walk is E.
So, the required distance is AE,
AE = 14 + 10 = 24 m
Hence, Vidya is 24 m away from the starting point.

BITSAT Logical Reasoning Test - 7 - Question 18

Directions: Read the given information carefully and answer the questions given below:
Karim travels 30 m towards north from his home, turns left and walks 25 m, again turns left and walks 50 m, then turns right and walks 15 m to reach his school.

In which direction is the school from his home?

Detailed Solution for BITSAT Logical Reasoning Test - 7 - Question 18

Explanation:

- Karim first travels 30 m towards north from his home.
- Then he turns left and walks 25 m.
- After that, he turns left again and walks 50 m.
- Finally, he turns right and walks 15 m to reach his school.

Therefore, the school is located in the South-west direction from his home.

BITSAT Logical Reasoning Test - 7 - Question 19

Directions: Read the given information carefully and answer the questions given below:
Rishi started early in the morning on the road towards the Sun. After some time, he turned to his left. Again, after some time, he turned to his right. After moving some distance, he again turned to his right and began to move.

At this time in what direction was he moving?

Detailed Solution for BITSAT Logical Reasoning Test - 7 - Question 19

Given that,
Rishi started walking in the morning on the road towards the Sun.
Then, he turned to his left.
Again, he turned to his right.
Then, he again turned to his right.
Since, early in the morning, the sun is in the direction of East, therefore, it is clear that he started in the direction of East.
After that, the rest of his movements are as follows:

From the above figure, it is clear that at this time he is moving in "South" direction.
Hence, option (D) is the correct answer.

BITSAT Logical Reasoning Test - 7 - Question 20

Directions: Read the given information carefully and answer the questions given below:
Raman walks 100 m from his house towards North. From there he goes 100 m towards west. Here is the house of shyam. From there they both goes to the market which is in the South-West direction from the Shyam's house.

If the market is in the west of Raman's house, then how far is the market from Raman's house?

Detailed Solution for BITSAT Logical Reasoning Test - 7 - Question 20

According to the problem,


Here, A is the starting point i.e., Raman's house. C is Shyam's house and D is the market.
From figure we can say,
AE and BC are parallel to each other with same lengths i.e., AE = BC = 100 m
AB and CE are parallel to each other with same lengths i.e., AB = CE = 100 m
From triangle DCE,
As we know that point D is in South-West to point C i.e., Shyam's house so we can say that ∠DCE = 45o and ∠CED = 90o
Now,
∠C + ∠D + ∠E = 180o
45o + 90o + ∠D = 180o
∠D = 180 − 135 = 45o
We know Tan 45o = 1, From triangle DCE,

CE = DE = 100 m
Now we have to find the distance between Raman's house and Market i.e., AD = AE + DE
= 100 + 100 = 200 m
Therefore the distance between Raman's house and market is 200 m.
