BITSAT Logical Reasoning Test - 7 - JEE MCQ

Mouth (3) - Oesophagus (4) - Stomach (1) - Intestine (2)
(Path of digestion of food in animal body)

Option (3) is the correct option.

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.

The pattern is a/b : b³/a³. The missing fraction is 3/4 : 64/27.

1) aac/baa/ccb/bbc - doesn't follow a pattern

2) abc/bba/ccb/abc - doesn't follow a pattern

3) abc/bca/cab/abc -  follows a pattern i.e. the letters a, b and c are repeated in each part

4) acc/bba/cab/cbc - doesn't follow a pattern

Hence, the correct answer is bcaa.

Given:

A and B are brother and sister respectively-

C is A's father-

D is C's sister and E is D's mother-

Therefore, B will be E's Granddaughter.

A person said that the man's (in the photograph) father is the son of his father. The person also said that he has no brothers or sisters, which means that he is the only child of his father.
Let us draw the family tree :

From the above diagram, it is clear that the person was the father of the man in the photograph.
Hence, the person is looking at his son's photograph.

Based on the question:
F is A's brother. C is the daughter of A. J is the brother of C.
C and J are children of A. J is the son of A.
K is the sister of F.
As we know, F is A's brother, thus, K, F and A are siblings.

Thus, F is the uncle of J.

Draw the family tree:

Let us take the information one by one accordingly:-
We can draw the family tree like:

As, D is the brother-in-law of B's father, D is the brother of B's mother. As, B is the sister of A and A is the child of X.
So, X is the mother of A. Thus D is the brother of X.
Hence, the correct answer will be option (C): Brother.

Following symbols are used to solve the blood relation problem:

Draw the relationship diagram from the given relationship.

Clearly, C is the nephew of E.

Based on the given information, the relationship of all is as follows, D is the husband of C, and A is the mother of C, therefore, A is the mother-in-law of D.
Hence, Mother-in-law is the correct answer.
It can also be expressed by the figure:

Given that:
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.
Thus, the lady is sister of the man.
In the family tree diagram given below, circles show males and squares show females.

Hence, option (D) will be the correct answer.

According to question
The mother of the mother of the woman is the maternal grandmother of the woman and the only son of the maternal grandmother is the maternal uncle of the woman. Hence the man is the maternal uncle of the woman.

According to the question,
A relationship diagram can be drawn as follows:

From the above figure, it is clear that:
A's wife is C.
E's wife is D.
A is the brother of E.
F is only the unmarried male.
D and C both are females and A, B, E and F are males.
So the four members of the same family are A, C, D and E.
B and F are colleagues in the same organisation and there is no family relation given between "B" and "F".
Hence, the given data is inadequate to answer the question.

According to the question, 
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.

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.

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.

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.

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.

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 = 45^o and ∠CED = 90^o
Now,
∠C + ∠D + ∠E = 180^o
45^o + 90^o + ∠D = 180^o
∠D = 180 − 135 = 45^o
We know Tan 45^o = 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.
