SSC CGL Exam Previous Asked Questions with Explanations
1) Sarita and
Julie start walking from the same place in the opposite directions. If Julie
walks at a speed of 2½ kmph and Sarita at a speed of 2 kmph, in how much time
will they be 18 km a part? [SSC CGL Exam 20/07/2014]
a) 4.0 hrs
b) 4.5 hrs
c) 5.0 hrs
d) 4.8 hrs
Sarita and Julie Speed is 2½ kmph + 2 kmph = 4½ kmph
Distance = Speed x Time
18 km = 4.5 kmph x Time
18 km/4.5 kmph = Time
4hrs = Time
2) A man travels
¾th of the distance of his journey by bus, 1/6th by
rickshaw and 2 km on foot. The total distance travelled by the man is: [SSC
CGL Exam 08/09/2016]
a) 12 km
b) 18 km
c) 20 km
d) 24 km
Suppose Total Distance ‘D’
(3/4)D + (1/6)D + 2 = D
3D/4 + D/6 + 2 = D
D – (3D/4 + D/6) = 2
12D – (9D + 2D)/12 = 2
12D – 11D = 24
D = 24
3) To cover a
certain distance with a speed of 60 kmph, a train takes 15 hours. If it covers
the same distance in 12 hours, what will be its speed? [SSC
CGL Exam 09/09/2016]
a) 65 kmph
b) 70 kmph
c) 75 kmph
d) 80 kmph
Distance = Speed x Time
Distance = 60 kmph x 15 hrs
Distance = 900 km
Distance = Speed x Time
900 km = Speed x 12 hrs
900 km/12 hrs = Speed
75 kmph = Speed
4) Sound travels
at 330 meters per second. The distance (in kilometer) of a thunder cloud when
its sound follows the flash after 10 seconds is: [SSC CGL Exam
10/09/2016]
a) 0.33 km
b) 3.3 km
c) 33 km
d) 33.3 km
Distance = Speed x Time
Distance = 330 mps x 10 Sec
Distance = 3300 meters
Distance = 3.3 km

8) A and B are 20
km apart. A can walk at an average speed of 4 kmph and B at 6 kmph. If they
start walking towards each other at 7 a.m., when they will meet? [SSC
CGL Exam 19/10/2014, Shift I]
a) 8.00 a.m.
b) 8.30 a.m.
c) 9.00 a.m.
d) 10.00 a.m.
A Speed + B Speed is 4 kmph + 6 kmph =
10 kmph
They can walk 10 km in one hour. To
walk next 10 km, they can take another one hour
To walk 20 km, they can take 2 hours.
So 7 a.m + 2 hours is 9 a.m
9) A train
travels 500 meters in first minutes. In each minute 125 meters more than that
in the previous minute. The average speed per hour of the train during those 5
minutes will be [SSC CGL Exam 30/08/2015]
a) 30 kmph
b) 45 kmph
c) 50 kmph
d) 55 kmph
(500 x 5) + [125(1+2+3+4)]
2500 + 125(10)
2500 + 1250
3750
Distance is 3750 meters
Distance = Speed x Time
3750 m = Speed x 5 min
3750 m = Speed x 5 x 60 Sec
(3750/300) mps = Speed
(3750/300) x (18/5) kmph = Speed
45 kmph = Speed
10) At an average
of 80 kmph Shatabdi Express reaches Tanchi from Kolkata in 7 hrs. The distance
between Kolkata and Ranchi is [SSC CGL Exam 09/09/2016, Shift II]
a) 560 km
b) 506 km
c) 560 m
d) 650 m
Distance = Speed x Time
Distance = 80 kmph x 7 hrs
Distance = 560 km
11) A train
without stoppage travels with an average speed of 72 kmph and with stoppage, it
travels with an average speed of 60 kmph. For how many minutes does the train
stop on an average per hour? [SSC CGL Exam 11/06/2019, Shift II]
a) 10
b) 12
c) 6
d) 8
A train travels 72 km in one hour. One hour means 60 minutes
60 ------------- 72
? -------------- 60
(60 x 60) / (72 x ?)
? = 50
60 – 50 = 10 minutes
12) A train
without stoppage travels with an average speed of 50 kmph and with stoppage, it
travels with an average speed of 40 kmph. For how many minutes does the train
stop on an average per hour? [SSC CGL Exam 10/06/2019, Shift II]
a) 12
b) 14
c) 13
d) 15
A train travels 50 km in one hour. One hour means 60 minutes
60 ------------- 50
? -------------- 40
(60 x 40) / (50 x ?)
? = 48
60 – 48 = 12 minutes
13) A car travels
80 km in 2 hours and a train travels 180 km in 3 hours. The ratio of the speed
of the car to that of the train is: [SSC CGL Exam 04/09/2016, Shift
III]
a) 2 : 3
b) 3 : 2
c) 3 : 4
d) 4 : 3
A car travels 80 km in 2 hours. So it can travel 40 km in one
hour
A train travels 180 km in 3 hours. So it can travel 60 km in one
hour
40 : 60
2 : 3
14) If I walk at 5kmph, I
miss a train by 7 minutes. If, however, I walk at 6 kmph, I reach the station 5
minutes before the departure of the train. The distance (in km) between my

a) 6
b) 5
c) 4
d) 3
Distance ‘D’
(D/5) – (D/6) = (12/60)
(6D – 5D)/ 30 = 1/5
D = 30/5
D = 6
15) Sound travels
330 meters in a second. When the sound follows the flash of lightning after 10
seconds the thunder cloud will be at a distance of: [SSC
CGL Exam 27/10/2016, Shift I]
a) 1300 meters
2) 2000 meters
c) 3650 meters
d) 3300 meters
Distance = Speed x Time
Distance = 330 mps x 10 sec
Distance = 3300 meters
16) Two persons
ride towards each other from two places 55 km apart, one riding at 12 kmph and
the other at 10 kmph. In what time will they be 11 km apart? [SSC
CGL Exam 02/09/2016, Shift II]
a) 2 hours and 30 minutes
b) 1 hours and 30 minutes
c) 2 hours
4) 2 hours and 45 minutes
The speed of two persons is 22 kmph
(12 kmph and 10 kmph)
They go for one hour is 22 km
For two hours 44 km
55 km – 44 km
11 km
