Look at Meeta's father's and brother's statement carefully. According to their statement it is clear that Meeta's father birthday is after 10th July but before 12th July. Thus, we can conclude that the birthday was on 11th July.
A is 18th from front and C is 24th
Number of persons between A and C = 6.
Since C is exactly in middle of A and B, so number of persons between C and B = 6.
? Number of persons in the queue = (17 + 1 + 6 + 1 + 6 + 1 + 15) = 47.
Clearly, according to the given conditions, there are 15 boys to the left of A, as well as to the right of C. Also, B lies between A and C such that there are 3 boys between A and B and 4 boys between B and C. So, number of boys in the row = (15 + 1 + 3 + 1 + 4 + 1 + 15) = 40.
After interchanging their positions, position of A from left = 11
Then positions of A from right = 9.
?The total no. of people in the row
= (9 + 11) ? 1 = 19.
Here (i) weakens the statement whereas (ii) and (iii) support and strengthen the statement. But (iv) and (v) neither weaken nor strengthen the statement. In order to decide whether a statement strengthens(or weakens) an argument, follow these steps.
Step I: Break up the argument mentally. See what is the supporting premise, what is the assumption and what is the conclusion.
Step II: If a suggested statement supports any of the three it would be a strengthening statement. If it contradicts any of the three it would be a weakening statement. In order to decide which statement strengthens (or weakens) an argument the most, follow an additional step:
Step III: If a suggested statement supports (or weakens) the basic assumption of an argument, it would be the most strengthening (weakening) argument. Or If a suggested statement provides a very strong proof (or contradictory proof) in favour of (or in contradiction to) the conclusion of the argument, it would be the most strengthening (or weakening) statement.
Since Rita and Monika exchange places, so Rita's new position is the same as Monika's earlier positions. This position is 17th from the right and 10th from the left
? Number of girls in the row = (16 + 1 + 9) = 26.
Given that :- The day before yesterday was Friday.
Therefore, today is Sunday.
The day after-tomorrow will be Tuesday .
? Tuesday + 3 days = Saturday
Hence , the third day after the day after tomorrow will be Saturday .
Given that :- The day after tomorrow is Sunday.
Therefore, today is Friday.
The day on tomorrow's day before yesterday = Friday ?1 day = Thursday
Therefore,required answer is Thursday .
Here , Two weeks earlier than 23rd was also Sunday.
23rd ? 7 days = 16
16th ? 7 days = 9
4 days earlier than 9 - 4 days = 5th
9th ? Sunday
8th ? Saturday
7th ? Friday
6th ? Thursday
5th ? Wednesday
Hence , required answer will be Wednesday .
Given that :- The day after tomorrow is Tuesday.
? Two days after Tuesday will be Thursday.
