Rahul Gupta answered
From statement I, we know that the man in the photograph is the only son of Tanya's grandfather. This means that Tanya is either the man's daughter or granddaughter.

From statement II, we know that the man in the photograph has no brothers or sisters and his father is Tanya's grandfather. This confirms that Tanya is the man's daughter or granddaughter.

Combining both statements, we can conclude that Tanya is either the daughter or granddaughter of the man in the photograph.

Correct answer is option 'D'. Can you explain this answer?

BT Educators answered
  • Statement I: H is the only daughter of X, who is the wife of M. This means M has at least one child (H, the daughter). Therefore, this statement alone is sufficient to answer that M has one child.
  • Statement II: K and J are brothers of M. This information provides no direct insight into how many children M has, as it talks about M's brothers, not M's children. Therefore, this statement alone is not sufficient to answer the question.
Hence, Statement I alone is sufficient, while Statement II alone is not sufficient to answer the question.

Arya Mehta answered
Since 8th to the left of 12th from the right is 20th from the right, so from I, we know that Vishakha is 5th from left and 20th from right i.e. there are 4 children to the left and 19 to the right of Vishakha. So, there are (4 + 1 + 19) i.e. 24 children in the row.
From II, Nisha is 7th from right and 18th from left end of the row.
So, there are (6 + 1 + 17) = 24 children in the row.

Saanvi Rane answered
Statement Analysis:

Statement I: Each entry pass holder can take up to three persons with him/her.
- This statement provides information about the number of people allowed per entry pass holder, but it does not give the total number of visitors.

Statement II: In all, 243 passes were sold yesterday.
- This statement gives the total number of passes sold, but it does not specify how many people actually visited the exhibition.

Combined Analysis:
- Statement I gives the limit on the number of people per pass holder, but it does not give the actual number of pass holders.
- Statement II provides the total number of passes sold, but it does not specify how many people each pass holder brought with them.
- Without knowing the exact number of pass holders and how many people each pass holder brought, we cannot determine the total number of visitors.
- Therefore, the data given in both statements I and II together are not sufficient to answer the question.
- The correct answer is option (D) Neither I nor II is sufficient.

Correct answer is option 'C'. Can you explain this answer?

Ankita Dey answered
Understanding the Question
The question asks which number represents "button" in a specific code language. The provided information consists of two statements that may help decode the meanings of numbers related to the term "button."
Statement I Analysis
- Content: 926 means "clip your tie."
- Implication: This statement does not mention "button" at all. It only relates to "clip" and "tie," which makes it insufficient to determine which number corresponds to "button."
Statement II Analysis
- Content: 175 means "hole and button."
- Implication: Here, "button" is explicitly mentioned along with "hole." However, without knowing what each number stands for, we cannot conclude which specific number represents "button."
Combining Statements I and II
- From Statement I: We learn about the numbers related to "clip" and "tie."
- From Statement II: We learn about "hole" and "button."
By analyzing both statements together, we can deduce that:
- The number for "button" is part of the number combination in Statement II (175).
- Since none of the numbers in Statement I overlap with those in Statement II, they do not provide conflicting information.
Conclusion
Since either statement on its own does not provide enough information to isolate the number for "button," but both statements together lead us to the conclusion regarding the number associated with "button," the correct answer is:
Option C: Either I or II is sufficient.

Question -
 
Question: In a certain code, '13' means 'stop smoking' and '59' means 'injurious habit'. What do '9' and '5' mean respectively in that code ?
Statements:
I.
'157' means 'stop bad habit'.

II.'839' means 'smoking is injurious'.
 
 
  • a)
    I alone is sufficient while II alone is not sufficient
  • b)
    II alone is sufficient while I alone is not sufficient
  • c)
    Either I or II is sufficient
  • d)
    Neither I nor II is sufficient
  • e)
    Both I and II are sufficient
Correct answer is option 'C'. Can you explain this answer?

'59' means 'injurious habit' and '157' means 'stop bad habit' (from I). Thus, the common code number '5' stands for common word 'habit'. So, '9' represents 'injurious'. Hence, I is sufficient.
Also, '59' means 'injurious habit' and '839' means 'smoking is injurious'. Thus, the common code number '9' stands for common word 'injurious'. So, '5' represents 'habit'. Thus, II is also sufficient.,

Question: Which word in the code language means 'flower' ?
Statements:
I.
'de fu la pane' means 'rose flower is beautiful' and 'la quiz' means 'beautiful tree'.

Correct answer is option 'D'. Can you explain this answer?

Deepak Basu answered
Understanding the Question
The question asks which word in a coded language means "flower". We are given two statements to analyze the available information regarding the codes for various words.
Analyzing Statement I
- Statement I: "de fu la pane" means "rose flower is beautiful" and "la quiz" means "beautiful tree".
From this statement:
- We know that "la" means "beautiful" (common in both phrases).
- The word "fu" is likely related to "rose" since it appears in the context of flowers.
- However, we do not have explicit information about the word for "flower".
This means Statement I alone is not sufficient to determine which word means "flower".
Analyzing Statement II
- Statement II: "de la chin" means "red rose flower" and "pa chin" means "red tea".
From this statement:
- The word "chin" is common, indicating it means "red".
- Here, "de" is likely "flower" because it connects with "rose" in the phrase "red rose flower".
Thus, Statement II alone provides sufficient information to conclude that "de" means "flower".
Conclusion
- Statement I alone does not provide enough information about the word for "flower".
- Statement II alone is sufficient, as it directly includes the word associated with "flower".
Therefore, the answer is option 'D': Statement II alone is sufficient while Statement I alone is not sufficient.

Question -
 
Question: Among A, B, C, D, E and F, who is the heaviest ?
Statements:
I.
A and D are heavier than B, E and F but none of them is the heaviest.

II.A is heavier than D but lighter than C.
 
 
  • a)
    I alone is sufficient while II alone is not sufficient
  • b)
    II alone is sufficient while I alone is not sufficient
  • c)
    Either I or II is sufficient
  • d)
    Neither I nor II is sufficient
  • e)
    Both I and II are sufficient
Correct answer is option 'A'. Can you explain this answer?

Statement Analysis:

Statement I:
- A and D are heavier than B, E and F but none of them is the heaviest.

Statement II:
- A is heavier than D but lighter than C.

Explanation:

Comparing A and D:
- From Statement I, we know that A and D are heavier than B, E, and F.
- From Statement II, we know that A is heavier than D.
- Therefore, A must be the heaviest among A, D, B, E, and F.
- However, we cannot determine who is the heaviest among A, B, C, D, E, and F as the weight comparison with C is not provided in Statement I.
Therefore, the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question. Hence, the correct answer is option 'A'.

Ritika Yadav answered
Statement Analysis:

Statement I:
- Only boys play football.
- This statement alone does not provide a specific number of students playing football since the total number of boys in the class is not given.

Statement II:
- There are forty boys and thirty girls in the class.
- This statement alone does not provide the information on how many students play football as it does not specify whether girls play football or not.

Combined Analysis:
- Combining both statements, we know that there are forty boys in the class, but we do not know if all boys play football.
- Additionally, we are not provided any information about the girls playing football.
- Therefore, even when the two statements are considered together, we cannot determine the exact number of students who play football.
Therefore, the correct answer is option D) Neither I nor II is sufficient.
