**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

E)Data inadequate

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

A)Only I & II together

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)
