Answers & Solutions for Time and Work Questions for SBI PO PDF:
1) Answer (D)
All the three friends will meet at the starting point again after X seconds, such that X is the LCM of the times taken by J, K and L to complete one round.
=> LCM of 12, 18 and 20 = 180 seconds = 3 minutes.
Hence 3 minutes is the answer.
2) Answer (E)
Let the speed of boat in still water be v and the speed of water be x.
Boat speed while going upstream = v-x = 28
Boat speed while going downstream = v+x = 32
=> 2v = 60 => v = 30
Hence, none of these is the correct answer.
3) Answer (A)
Suppose the required distance be d km/h
Then, d/4 – d/5 = 15min = 1/4 h ⇒ d 1/20 = 1/4 ⇒ d = 5km.
4) Answer (D)
Speed downstream = (15 + 3) kmph = 18 kmph.
Distance traveled =(18×12/60)km = 3.6 km.
5) Answer (D)
Time taken to cover 375 km = (375 / 75)h = 5h
Number of stoppages = 375 / 125 – 1 = 2
Total time to stoppages = (5 × 2 ) min = 10 min
Hence, total time taken = 5 h 10 min
6) Answer (C)
With the current => downstream
Against the current => upstream
Let the speed of the boat be ‘s’ and the speed of the river be ‘r’.
So, s – r = 5 and s + r = 15
=>2s = 20 => s = 10 and r = 5 kmph
Speed of the current = 5 kmph
7) Answer (C)
Speed of train = x
Relative speed = x + 9(5 / 18) = x + 2.5
Speed = 210 / 6 = 35 m/s
x + 2.5 = 35 => x = 32.5 m/s = 32.5 * (18/5) = 6.5 * 18 = 117 kmph
8) Answer (E)
We know the formula of speed which is Speed = Distance/Time
Speed of a truck = 640/10 = 64
Speed of a car = 640/8 = 80
Ratio of speed of truck and car = 64:80 = 4:5
9) Answer (B)
Number of days in 4 weeks = 4*7 = 28
Since Faisal walks 325 m every day
Distance walked in 28 days = 325*28 = 9100 m
9100 m = 9.1 km
10) Answer (C)
Length of the train = 280 m
Length of the platform = (280*3) m
Since the train passes the platform completely
Total distance traveled by train = 280 + (3*280) = 4*280
Time take = 6 min 40 s = 360 + 40 = 400 s
Speed = 4*280 / 400 = 2.8 m/s.
