Answers and Solutions for Time and Distance Questions for SSC CGL PDF:
1) Answer (D)
Total time taken to reach Raju’s school = 30 / 10 + 30 / 30 = 3 + 1 = 4hrs.
2) Answer (D)
Distance he covers = 6.5*18 = 117 km
Time taken by the man to cover the distance while running = 117/12 = 9.75 hours
3) Answer (C)
60 seconds = 1/60 hours
Sum of the lengths of the trains = (sum of the speeds of the trains)*time taken = (30+120)*(1/60) = 2.5 km
4) Answer (C)
The speed in still water is 20 m/min
Speed of the water current is 0.24 km/hr = 4 m/min
=> Speed of the boat upstream = 16 m/min => Time upstream = 576/16 = 36 min
Speed of the boat downstream = 24 m/min => Time downstream = 576/24 = 24 min
=> Difference in time = 36-24 = 12 min
5) Answer (C)
Speed = Distance / Time
Speed of the train = 480/32 = 15 m/s
To convert m/s to km/hr we need to multiply by 18/5
So Speed = 15*18/5 = 54 km/hr
6) Answer (A)
Let us assume that each man does 1 unit of work each day.
So, the total work to be done is 10 X 4 = 40 units
Now, on the first day 10 workers will work, on the second day 9 workers will work, on third 8 and so forth.
Since each man does 1 unit of work, the work done on each day can be written as-
10(1st day) + 9(2nd day) + 8(3rd day) + 7(4th day) + 6 (5th day) = 40 units
Thus, the assignment will get completed on the 5th day.
7) Answer (D)
Marked Price = Rs. 100
After successive discount of 10% and 20% ,
Therefore, Cost Price becomes => ( 0.90 ) x ( 0.80 ) x 100 = 72
Since, there is a Transportation Cost as well
Total Cost Price => ( 1.10 ) x 72 = Rs. 79.20
To gain 5%, Selling Price of the dealer should be => Rs.( 1.05 ) x ( 79.20 ) = Rs. 83.16
8) Answer (C)
Let his normal speed be ‘s’.
So, the distance will be 180s. (3 hours = 180 minutes)
But he leaves his house 45 minutes late. So, the time left is 135 minutes.
Let the speed in this case be s’.
=> 135s’ = 180s
=> s’/s = 4/3
Thus, he needs to increase his speed by a factor of 1/3 or 33.33%
9) Answer (B)
The amount of work done by Amit in 3 days is equal to the amount of work done by Vinod in 2 days. Hence if Amit does 1 unit of work in 3 days, Vinod can do it in 2 days. In 15 days, Amit would do 15/3 = 5 units of work.
The time needed by Vinod to complete 5 units of work = 5*2 = 10 days.
10) Answer (D)
Let the total work to be done be 60 units. So Ram does 4 units of work in a day and Shyam does 3 units of work in a day. Hence when they work together, they will be able to do 7 units in 1 day.
Hence in 5 days, they will do 35 units of work. Thus, the remaining 25 units will have to be done by Shyam. The time taken by Shyam to do the remaining 25 units of work = 25/3 = 8.33 days.
Hence the total time taken = 5 + 8.33 = 13.33 days.
Hence the work will be completed on 14th day.
