Quantitative Aptitude– Data Sufficiency- For Bank & Insurance

# Quantitative Aptitude– Data Sufficiency- For Bank & Insurance Dear Readers, Expected Data Sufficiency questions for Bank/Insurance was given here. Aspirants those who are preparing for the examination can use this.

Quantitative Aptitude– Data Sufficiency (Time & Distance) – Set 11

Directions(1-3) Each of the questions below consist of a question & two statements numbered I & II given below it. You have to decide whether the data provided in the Statement are sufficient to answer the question. Read both the statements & give answer.

A)If 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
B) If the data in statement II alone are sufficient to answer the question , while the data in statement I alone are not sufficient to answer the question
C)If the data either in statement I alone or in statement II alone are sufficient to answer the question.
D)If you cannot get the answer from the statement I & II together , but need even more data
E)If the data in both statement I & II together are necessary to answer the question

1)What is the speed of running train ?
I)The train crosses a signal post in 6 seconds
II)The train crosses another train running in the opposite direction in 15 seconds

2)What is the speed of the running train ?
I)The length of the train was 180 mt
II) It crossed a standing train whose length was 180 m in 4 seconds

3)How much time will Train M take to cross Train N running in opposite direction(towards each other )
I)Tran M can cross a signal pole in 21 sec. It can cross 440 m long station in 43 sec
II)The respective ratio of speeds of Train M & train N is 2 : 3 . The sum of the length of the Train M & Train N is 700 m.

Directions (4-5)You have to determine which statements(s) is /are sufficient /necessary to answer the questions.
4)A person travels by car from A to B & from B to A . How long will it take to travel both the ways by car ?
I)It takes 4 hours in travelling from A to B by train& returning by car
II)The distance between the two places is 325 km
III)If he travels by bus he takes 3 hours more .

A)All three statements even together are not sufficient
B)Only II
C)Only III
D)Either I or III

5)How much time will train A take to cross another train B running in opposite direction ?
I)240-metre long train A crosses a signal pole in 6 seconds
II)The ratio of the speed of train A to that of train B is 3 : 2
III)Train B crosses a platform of length 580 m in 5 sec

B)Only II & III together
C)Only I & III together
D)All together are necessary
E)None of these

Ans
1.D)
From I & II . The length of the train is not give.
Thus the speed of the train can’t be determined without the distance ( length of train )
2.E)
From I-Time is not given . So we can’t find the speed of the train
From II-Speed of the train = (180+180)/4=90 m/sec
3.E)
From statement I & II
Let the length of train M = X mt.
According to question X/21= (X+440)/43
X=420 mt
Length of train N =700-420=280 m
Speed of train M=42/21=20 m/sec
Speed of train N = (3/2)* 20= 30 m/sec
Required time = 700/(30+20)=14 sec.
4.A).
From I- he travels by train . So we can’t find the travel time
From II-Nothing is said about the speed of the car, so we can’t find the answer
From III- we have to find the travel time by car not by bus
Therefore we can’t find the answer from all the statements together.
5.D)
