Answers and Solutions forĀ  IBPS Clerk Time and Work Questions:

Solutions:

Least common multipke of 36,27 and 9 is 108.
Hence Harish, Dilip and Asha will meet at 108 second i.e 1 minute and 48 seconds.
Therefore, the correct option is option A.

LCM of 12, 18 and 20 = 180
Hence, they’ll meet again after 180 seconds => 3 minutes.

Let the speed of boat be b and that of water be w.
Hence, b+w = 32
and b-w = 28
Adding both eqns together, 2b = 60
b=30km/hr

Length of platform = 200*2 = 400
The actual distance covered by train in 36 seconds = Length of platform + Length of train = 400+200= 600
Speed of the train = 600/36 = 16.67m/s = 60km/hr
Hence, ther correct option is A.

Speed of the truck = 360/8 = 45 km/hr
Now,
Speed of the car = 360/6 = 60km/hr
Ratio of speed of truck and car = 45/60 = 3:4
Therefore, option B is correct.

Number of days in 5 weeks = 5*7 = 35 days
Number of kilometres wallked in one day = 0.226 kilometres
Number of kilometres walked in 35 days = 0.226 * 35 = 7.91 km
Hence, option B is the correct answer.

The time of their meeting again can be calciulated by taking LCM of 24, 6 and 14.
LCM of 24, 6 and 14 = 168
Now, 168 seconds = 2 min 48 s.
Option D is correct.

The length of platform = 2*length of train = 2*240 = 480
Total distance covered by train = Length of platform + Length of train = 480+240 = 720
Speed of train = 720/120 = 6m/s
Hence, the correct option is option C.

Let the speed of the train be x m/s
Speed of the man = 5km/hr = 1.388m/s
Relative speed of man when he is running in opposite direction = (x+1.388)
However train crossess him in 36 seconds = 350/36 = 9.722 m/s
x+1.388 = 9.722
x = 8.334 m/s
x = 30 km/hr
