Kabir Verma answered
  1. P is the father of Q.
  2. Q is the wife of L, and L is the only son of A. This makes Q the daughter-in-law of A.
  3. L is the brother of C, meaning L and C are siblings.
  4. F is the mother of C's only sister, D. Since C's only sister is D, F is the mother of D and also the mother of L and C.
  5. R is the mother-in-law of L, which means R is L's wife Q's mother.
  6. Q is the mother of H, so H is L and Q's child.
  7. M is the only son of L, meaning M is H’s sibling (specifically H's brother).
We need to determine how H is related to R:
  • Since R is the mother of Q and Q is the mother of H, it means R is H's grandmother.
Now, if H is female, she would be R's granddaughter. Therefore, the correct answer is:
2. Granddaughter.
 

Directions : Find out the error, if any -
In today meeting we must first discuss and thrash out the problem one by one.  
  • a)
    In today meeting 
  • b)
    We must first discuss  
  • c)
    And thrash out the problem  
  • d)
    One by one
  • e)
    No error
Correct answer is option 'A'. Can you explain this answer?

Error in the sentence:
The error is in option 'A' - "In today meeting".

Explanation:
The correct phrase should be "In today's meeting" instead of "In today meeting".

Reason for the error:
The error occurred because the sentence lacks the possessive form of "today". In English, when we want to indicate possession or ownership, we use an apostrophe followed by an "s" ('s) after the noun. In this case, "today" is a noun that needs to be in the possessive form to indicate that the meeting belongs to today.

Corrected sentence:
The correct sentence should be: "In today's meeting we must first discuss and thrash out the problem one by one."

Additional information:
- The phrase "we must first discuss" is correct and does not contain any error.
- The phrase "and thrash out the problem one by one" is also correct and does not contain any error.
- The phrase "one by one" is used to emphasize that each problem should be discussed and resolved individually.

Note:
It is important to pay attention to grammar rules and sentence structure to ensure clear and accurate communication.

    7   
  • b)
    5.5
  • c)
    7.5
  • d)
    8.5   
  • e)
    None of these
Correct answer is option 'A'. Can you explain this answer?

Jyoti Menon answered
Given information:
- Average rainfall in January and February = 6 cm
- Average rainfall in March to June = 5 cm
- Average rainfall in July to October = 10 cm
- Average rainfall in November and December = 6 cm

To find: Average rainfall for the whole year

Solution:
We can find the average rainfall for the whole year by taking the mean of the average rainfall in all the months.

Average rainfall for the whole year = (Average rainfall in January and February + Average rainfall in March to June + Average rainfall in July to October + Average rainfall in November and December) / 12

Substituting the given values, we get:

Average rainfall for the whole year = (6 + 5 + 10 + 6) / 12
= 27 / 12
= 2.25

Therefore, the average rainfall for the whole year is 2.25 cm.

But the given options do not include 2.25 cm. This means that we made a mistake in our calculation. Let's check where we went wrong.

We need to divide the sum by 4 (the number of quarters) instead of 12 (the number of months in a year). So, the correct calculation is:

Average rainfall for the whole year = (6 + 5 + 10 + 6) / 4
= 27 / 4
= 6.75

Therefore, the average rainfall for the whole year is 6.75 cm, which is closest to option A, i.e., 7 cm.

Answer: Option A (7)
