Questions and Answers

Q 1 - A competitor runs 200 meters race in 24 seconds. His rate is:

A - 20 km/hr

B - 24 km/hr

C - 28.5 km/hr

D - 30 km/hr

Answer : D

Explanation

Speed = 200/24 m/sec = (200/24* 18/5) km/hr = 30 km/hr

Q 2 - A man covers half of his adventure at 6km/hr and the staying half at 3 km/hr. His normal rate is:

A - 3 km/hr

B - 4km/hr

C - 4.5 km/hr

D - 9 km/hr

Answer : B

Explanation

Average speed = 2xy/(x+y) km/hr =  2*6*3/(6+3)km/hr = 4 km/hr

Q 3 - If an understudy strolls from his home to class at 5km/hrs, he is late by 30 min. However, on the off chance that he strolls at 6 km/hr. he is late by 5 min. just. The separation of his school from his home is:

A - 2.5 km

B - 3.6 km

C - 5.5 km

D - 12.5 km

Answer : D

Explanation

Let the required distance be x km. then,
x/5 - x/6 = 25/7   (difference between two times is 25 min.)
⇒ 12x- 10 x = 25 ⇒2x = 25   ⇒ x= 25/2 km = 12.5 km

Q 4 - A and B begin all the while from a sure point in North and South bearings on engine cycles. The velocity of A is 80 km/hr and that Of B is 65 km/hr. What is the separation in the middle of A and B following 12 minutes?

A - 14.5 km

B - 29 km

C - 36.2 km

D - 39 km

Answer : B

Explanation

Required distance = sum of distance covered by A and B
= {(80*12/60) + (65*12/60)} = (16+13) = 29 km

Q 5 - The velocities of three autos in the proportion 2:3:4. The proportion of the times taken by these autos to venture to every part of the same separation is:

A - 2:3:4

B - 4:3:2

C - 4:3:6

D - 6:4:3

Answer : D

Explanation

Ratio of time taken = 1/2: 1/3: 1/4 = 6:4:3

Q 6 - A constable is 114 m behind a thief. The constable runs 21 m and the thief15 m in a moment. In what the reality of the situation will become obvious eventually constable catch the criminal?

A - 16 min

B - 17 min

C - 18 min

D - 19 min

Answer : D

Explanation

(21-15) m i.e.6m is covered in 1 min.
114m will be covered in (1/6*114) min=19 min.

Q 7 - The separation between two stations A and B is 220 km. A train leaves a towards B at 80 km/hr. After thirty minutes, another train leaves B towards An at 100 km/hr. The separation of the point where the two trains meet, from A is:

A - 120 km

B - 130 km

C - 140 km

D - 150 km

Answer : A

Explanation

Let the required distance be x km. then,
x/80 - (220-x)/100 = 1/2
⇒ 5x-4 (220-x) = 200 ⇒9x = 1800 ⇒x = 120
Hence the required distance is 120 km.

Q 8 - Laxman needs to cover 6 km in 45 minutes. On the off chance that he covers one portion of the separation in 2/3 rd time, what ought to be his rate to cover the remaining separation in the remaining time?

A - 12 km/hr

B - 16 km/hr

C - 8 km/hr

D - 6 km/hr

Answer : A

Explanation

Time left = (1/3*45/60)hr = 1/4 hr, distance left = 3 km
Speed required = 3/ (1/4) km/hr = 12 km/hr

Q 9 - A auto covers four progressive 3 km extends at 10 km/hr, 20 km/hr, 30 km/hr and 60 km/hr separately. Its normal rate over this separation is:

A - 10 km/hr

B - 20 km/hr

C - 25 km/hr

D - 30 km/hr

Answer : B

Explanation

Total distance = (3*4) km = 12 kms
Total time taken = (3/10+3/20+3/30+ 3/60) = (36+18+12+6)/120 hrs.
= 72/120 hrs = 3/5 hrs.
Average speed = 12/ (3/5) km/hr = (12*5)/3 = 20 km/hr

Q 10 - A train voyaged separations of 10 km, 20 km and 30 km at rates of 50 km/hr, 60 km/hr and 90 km/hr separately. The normal rate of the train was

A - 60 km/hr

B - 66.67 km/hr

C - 69.23 km/hr

D - 65 km/hr

Answer : C

Explanation

Total distance covered = (10+20+30) km = 60 km
Total time taken = (10/50 + 20/60+ 30/90) hr = (1/5+1/3+1/3) hr = 13/15 hr.
Average speed = (60* 15/13) km/hr = (900/13) km/hr = 69.23 km/hr
