Raj and Sam are standing in a row facing same direction. Raj is 15th from right and Sam is 14th from left.
Q. How many persons are there in the row?
I. If Sam shifts 5 places to the left then there will be 7 persons between Raj and Sam.

Try yourself:Directions: In the following problem, a question followed by three statements (I), (II) and (III) is given. You have to determine which statement(s) is/are sufficient/necessary to answer the question.
In a certain code language, 'what' is written as 'ta', how is 'day time' written in that code language? (Sequence of codes does not matter)
Q. I. In that code language, 'how was your day' is written as 'ry as wo yo' and 'give me some time' is written as 'mo ni me mi'.
II. In that code language, 'what time of day' is written as 'mi ta if ry' and 'how is your work' is written as 'so wo yo la'.
III. In that code language, 'time is not good' is written as 'so mi to do' and 'good time of you' is written as 'mi do if xo'.
Explanation
Using statements I and II:
'How was your day' and 'what time of day' have only one word common, which is day.
Hence, code for 'day' is 'ry'
'Give me some time' and 'what time of day' has only one word common, which is 'time'.
Hence, code for 'time' is 'mi'.
Using statements I and III:
We do not have any sentence, which has common words of sentence 'how was your day', hence we cannot find the code for day.
Using statements II and III:
Word 'time' is common in three sentences, hence code for 'time' is 'mi'.
'What time of day' and 'Good time of you' have common words 'time' and 'of'. Also, code for 'what' is known.
Hence, from 'what time of day', code for 'day' is 'ry'.
Statement II and either I or III are sufficient to answer the question.

Try yourself:Directions: The question given below is followed by three statements (I), (II) and (III). You have to determine which of the statements is/are sufficient/necessary to answer the question.
In a queue, Inder and Simu are standing with some other students where Simu is 14th from front and Inder is standing ahead of Simu.
Q. How many students are there in the queue?
I. The number of students standing ahead of Inder is 3 times the number of students standing between Inder and Simu.
II. The number of persons standing behind Simu is double the number of persons standing between Inder and Simu.
III. The number of persons standing behind Inder is one more than the number of persons standing ahead of Inder.
Explanation
Using statement I:
Let the number of students between Inder and Simu be x.
Number of students ahead of Inder = 3x
So, 3x +x + 1 = 13
x = 3
Using statements I and II:
Number of students behind Simu = 2x = 6
Total number of students = 14 + 6= 20
Using statements I and III:
Number of students ahead of Inder = 3x = 9
Number of students behind inder = 9 + 1 = 10
Total number of students = 9 + 1 + 10 = 20
Using statements II and III,
From statement II, we get
Number of person after simu = 2x
Total number of persons = 14 + 2x .....(1)
Also from statement III,we get:
Number of persons before Inder = 12-x
Number of persons after Inder = 12-x + 1
Total number of persons = 12 - x + 1 + 1 ....(2)
By equalising (1) and (2), total number of persons = 20
So, any two statements can be used to answer the question.

Q. What is the length of the platform?
(A) The train crosses a woman standing on the platform in 35 seconds.
(B) The train passes a station platform in 50 seconds and speed of the train is 72 km/hr.
(C) The length of the train is 700 m.
Explanation
From statement (B):
Speed of train = m/s = 20 m/s
From statement (A):
Time taken to cross the woman = 35 seconds
Thus, from (A) + (B), we have:
Length of train = 20 × 35 = 700 m
Let the length of platform be x metres.
Thus, total length = x + 700 m
Then, Speed = Length/Time
or, 1000 = x + 700
or, x = 300 m
Thus, length of platform is 300 m.
From (C): Length of the train is 700 m.
This statement alone is not necessary to find the length of the platform.
Thus, only statements A and B together are sufficient.
