Question 3. Two Trains 400m And 300m Long Run At The Speeds Of 50 Kmph And 40kmph Respectively In Opposite Directions On Parallel Tracks. The Time Taken To Cross Each Other?

Answer :

Trains are jogging in contrary Direction:

So want to find Length of Trains = 300m + 400m = 700m

and Total Speed = 40 Kmph + 50 Kmph (Opposite Direction)

= 90 Kmph

so velocity (m/sec) = 90 * 5/18 m/sec = 25 m/sec

Formula Used: Time = Distance/Speed

Time = 700/ 25 sec

Time = 28 Sec.

Question four. Two Stations A And B Are 110 Km Apart On A Straight Line. One Train Starts From A At 7 A.M. And Travels Towards B At 20 Kmph. Another Train Starts From B At 8 A.M. And Travels Towards A At A Speed Of 25 Kmph. At What Time Will They Meet?

Answer :

Let they meet x hours after 7 a.M.

Distance included by way of A in x hours = 20x km.

Distance protected by means of B in (x - 1) hours = 25(x - 1) km.

So Total Distance

=> 20x + 25(x - 1) = one hundred ten

=> 45x - 25 = a hundred and ten => 45x = 135

=> x = three.

As They meet x hrs after 7 a.M. So they meet at 10 a.M.

Question 5. Two Trains Are Running At forty Km/hr And 20 Km/hr Respectively In The Same Direction. Fast Train Completely Passes A Man Sitting In The Slower Train In 5 Seconds. What Is The Length Of The Fast Train?

Answer :

As educate are walking in same route

so Relative velocity = (40 - 20) km/hr = 20 km/hr

= ( 20 x 5/18 ) m/sec = 50/9 m/sec.

Formula Used: Distance = Speed * Time

Now Length of Faster Train = ( 50/nine x five ) m = 250/9 m

= 27 7/9 m.

Question 6. A Train Moves Past A Telegraph Post And A Bridge 264 M Long In eight Seconds And 20 Seconds Respectively. What Is The Speed Of The Train?

Answer :

Let the duration of the teach be x meters and its velocity by way of y m/sec.

Then, x/y = eight => x = 8y ----------- (1)

As according to the query overall distance = (x + 264) meters.

(x + 264)/20 = y

Put the value of x from equation 1.

=> 8y + 264 = 20y

=> y = 22.

Therefore Speed = 22 m/sec = ( 22 x 18 /5) km/hr = 79.2 km/hr.

Question 7. An Athlete Runs 200 Metres Race In 24 Seconds. His Speed Is?

Answer :

Speed = (200/24) m/sec = 25/3 m/sec

convert m/sec to km/hr

(25/3 * 18/5) km/hr = 30 km/hr.

Question 8. Albert Is Travelling On His Cycle And Has Calculated To Reach Point A At 2 P.M. If He Travels At 10 Kmph, He Will Reach There At 12 Noon If He Travels At 15 Kmph. At What Speed Must He Travel To Reach A At 1 P.M.?

Answer :

Let's Assume the space travelled Albert = x km.

Formula Used: Time = Distance/Speed

so (x/10 - x/15) = 2 hrs

=> (3x - 2x)/30 = 2 hrs.

=> (3x - 2x) = 60

x = 60 km.

Time taken to tour 60 km at 10 km/hr = 60/10 hrs = 6 hrs.

Formula Used: Speed = Distance/Time

So, Albert began 6 hours before 2 P.M. I.E @ eight A.M.

Required velocity = 60/five kmph. = 12 kmph.

Question nine. A Person Travelled By Train For 1 Hour At A Speed Of 50 Kmph. He Then Travelled By A Taxi For 30 Minutes At A Speed Of 32 Kmph To Complete His Journey. What Is The Average Speed At Which He Travelled During The Journey?

Answer :

Total distance travelled in 1 hour

= 50 + (&frac; x 32) km

= sixty six km

? Average velocity = Total distance/Total time

= sixty six/(3/2) = 44 kmph.

Question 10. A Car Covers Four Successive 6 Km Stretches At Speeds Of 25 Kmph, 50 Kmph, seventy five Kmph And a hundred and fifty Kmph Respectively. Its Average Speed Over This Distance Is?

Answer :

Time = Distance/Speed

Time taken for every 6 km can be given by using

6/25, 6/50, 6/75 and 6/one hundred fifty

Total time = (6/25) + (6/50) + (6/seventy five) + (6/a hundred and fifty) = (36 + 18 + 12 + 6)/150 = seventy two/a hundred and fifty

Average speed = Distance/time = (24/72) x a hundred and fifty = 50 kmph.

Question eleven. A' And 'b' Complete A Work Togather In eight Days.If 'a' Alone Can Do It In 12 Days.Then How Many Day 'b' Will Take To Complete The Work?

Answer :

A & B in the future paintings = 1/8

A alone in the future paintings = 1/12

B by myself at some point work = (1/eight - 1/12) = ( 3/24 - 2/24)

=> B sooner or later work = 1/24

so B can entire the work in 24 days.

Abaxis Aptitude Interview Questions
Question 12. If A Alone Can Do A Piece Of Work In 8 Days And B Alone Can Do The Same Work In 12 Days. How Many Days A And B Required To Finish The Same Work If They Work Togather?

Answer :

A on my own at some point work = 1/8

B on my own at some point paintings = 1/12

Both A and B sooner or later paintings = (1/eight + 1/12) = (three/24 + 2/24)

= five/24

so A and B collectively finish the paintings in 24/five day

or 4 4/five days.

Aptitude Interview Questions
Question thirteen. A Can Finish A Piece Work In 18 Days And B Can Do The Same Work In Half The Time Taken By A. So If They Working Together, What Part Of The Same Work Can Finished In A Day?

Answer :

First find the 1 day paintings of both (A & B)

A's 1 day's paintings = 1/18

and

B's 1 day's paintings = 1/9 (B can do paintings in 1/2 time)

(A + B)'s 1 day's paintings = (1/18+1/nine)

= (1+2)/18 = three/18 = 1/6

so A & B together can do 1/6 of labor in 1 day.

Question 14. A And B Can Together Finish A Work In 30 Days. They Worked Together For 20 Days And Then B Left. After Another 20 Days, A Finished The Remaining Work. In How Many Days A Alone Can Finish The Job ?

Answer :

(A + B)'s 1 day's work = 1/30

so (A&B) 20 days work = (20*1/30) = 2/three

so left work = (1?2/3)=1/3

1/3 work is accomplished by means of A = 20 days.

So entire paintings will be carried out through A = (20 x 3) = 60 days.

Question 15. A And B Together Can Do A Piece Of Work In 30 Days. A Having Worked For sixteen Days, B Finishes The Remaining Work Alone In forty four Days. In How Many Days Shall B Finish The Whole Work Alone ?

Answer :

A's 1 day's paintings = x

and B's 1 day's paintings = y

So (A & B) 1 day paintings = 1/30 => x+y =1/30

=> 30x + 30y = 1 -------- (1)

So 16x + 44y = 1 -------- (2)

By Solving above equations,

x = 1/60 and y = 1/60

B's 1 day's work = 1/60

Hence, B on my own shall end the entire paintings in 60 days.

overall time=1hr24min

A to T :: speed=4kmph

diistance=2/3S

T to S :: velocity=5km

distance=1-2/3S=1/3S

21/15 hr=2/three S/four + 1/3s /5

84=14/3S*three

S=eighty four*three/14*three

= 6km.

Question 17. A Cistern Can Be Filled By A Tap In four Hours While It Can Be Emptied By Another Tap In nine Hours. If Both Taps Are Opened Simultaneously, Then After How Much Time Will The Cistern Get Filled ?

Answer :

Time taken by using faucet A to fill the cistern=4 hrs

so work performed by means of faucet A in 1 hour = 1/4th

Time taken through tap B to drain the whole cistern = 9 hours

so paintings performed with the aid of tap B in 1 hour = 1/9th

=> Work done by way of (A + B) in 1 hour=(1/four - 1/nine)=five/36

Therefore, the tank will fill the cistern = 36/five hours=7.2 hours.

Question 18. In A Class, There Are 15 Boys And 10 Girls. Three Students Are Selected At Random. The Probability That 1 Girl And 2 Boys Are Selected, Is?

Answer :

Let's anticipate the pattern area = S

and Event of choosing 1 woman and a pair of boys = E

So, n(S) = Number ways of selecting 3 college students out of 25 = 25C3

=> (25 * 24 * 23)/(three * 2 * 1) = 2300.

N(E) = (10C1* 15C2)

= 10 * [(15 * 14)/(2 * 1)] = 1050.

P(E) = n(E)/n(S) = 1050/2300 = 21/forty six.

Question 22. Two Pipes A And B Can Fill A Tank In 9 Hours And three Hours Respectively. If They Are Opened On Alternate Hours And If Pipe A Is Opened First, In How Many Hours Will The Tank Be Full?

Answer :

Tank part crammed through pipe A in 1 hour =1/9

Tank component filled by pipe B in 1 hour =1/3

Given Pipe A and B are opened instead.

So Part stuffed in every 2 hours =(1/9+1/three)=4/9

Tank Part will be filled in 4 hour =2*four/nine=8/nine

Remaining component = (1-8/nine)=1/9

So subsequent is A flip.

So Pipe A will fill last 1/9 element in subsequent 1 hour.

Total Time = (4 hrs + 1 hrs) = 5 hrs.

Question 23. Pipe A Can Fill A Cistern In 6 Hours Less Than Pipe B. Both The Pipes Together Can Fill The Cistern In four Hours. How Much Time Would A Take To Fill The Cistern All By Itself?

Answer :

Let's expect time required with the aid of Pipe A to fill the cistern = X hours

So Time required through Pipe B to fill the cistern = (X + 6) hours

? Both Pipes (A+B) can fill cistern in 1 hour = [1/X + 1/(X + 6)]

Given Both pipe fill the cistern in 4 hours

=> [1/X + 1/(X + 6)] = 1/four => [(X+6) + X]/(X+6)*x = 1/four

4X + 24 + 4X = X2 + 6x

X2 - 2X - 24 = 0

(X-6)(X+four) = zero

=> A can fill cistern in 6 hours.

= (329.85/nine) = Rs. 36.Sixty five.

Question 26. Three Pipes A, B And C Can Fill A Tank In 6 Hours. After Working At It Together For 2 Hours, C Is Closed And A And B Can Fill The Remaining Part In 7 Hours. The Number Of Hours Taken By C Alone To Fill The Tank Is?

Answer :

Tank element stuffed through pipes (A+B+C) in 1 hrs = 1/6 ------- (1)

so tank part crammed with the aid of (A+B+C) in 2 hrs = 2*1/6 = 1/three

Now find the remaining part = (1-1/3) = 2/3

=> (A+B) 7 hs work = 2/3

so (A+B) 1 hrs paintings = 2/21 ------ (2)

To discover the C 1 hrs work use eq. 1 & 2

=> 1/6-2/21 = 1/14

so C by myself can fill the tank in 14 hrs.
