Six bells commence tolling together and toll at intervals of 2, 4, 6, 8, 10, and 12 seconds respectively. In 30 minutes, how many times do they toll together?
(a) 4
(b) 10
(c) 15
(d) 16
Ans: (d)
Sol: L.C.M. of 2, 4, 6, 8, 10, and 12 is 120 seconds (2 minutes).
In 30 minutes, they will toll together 30/2 + 1 = 16 times.
Let N be the greatest number that will divide 1305, 4665, and 6905, leaving the same remainder in each case. Then the sum of the digits in N is:
(a) 4
(b) 5
(c) 6
(d) 8
Ans: (a)
Sol: N = H.C.F. of (4665 – 1305), (6905 – 4665), and (6905 – 1305)
= H.C.F. of 3360, 2240, and 5600 = 1120.
Sum of digits in N = (1 + 1 + 2 + 0) = 4.
If a person walks at 14 km/hr instead of 10 km/hr, he would have walked 20 km more. The actual distance travelled by him is:
(a) 50 km
(b) 56 km
(c) 70 km
(d) 80 km
Ans: (a)
Sol:
A train can travel 50% faster than a car. Both start from point A at the same time and reach point B, 75 kms away from A, at the same time. On the way, however, the train lost about 12.5 minutes while stopping at the stations. The speed of the car is:
(a) 100 kmph
(b) 110 kmph
(c) 120 kmph
(d) 130 kmph

The angle of elevation of a ladder leaning against a wall is 60° and the foot of the ladder is 4.6 m away from the wall. The length of the ladder is:
(a) 2.3 m
(b) 4.6 m
(c) 7.8 m
(d) 9.2 m
Ans: (d) 9.2 m
Sol:
Let AB be the wall and BC be the ladder.
ACB = 60°, AC = 4.6 m
cos 60° = AC/BC = 1/2
BC = 2 × AC = 2 × 4.6 = 9.2 m
An observer 1.6 m tall is 20 m away from a tower. The angle of elevation from his eye to the top of the tower is 30°. The height of the tower is:
(a) 21.6 m
(b) 23.2 m
(c) 24.72 m
(d) None of these
Ans: (a) 21.6 m
Sol:
Let the height of the tower be h meters.
The height difference is given by tan 30° = (h – 1.6) / 20
√3/3 = (h – 1.6) / 20
h – 1.6 = 20 × √3/3
h = 20 × 1.73 / 3 + 1.6 = 11.54 + 1.6 = 21.6 m
From a point P on a level ground, the angle of elevation of the top of a tower is 30°. If the tower is 100 m high, the distance of point P from the foot of the tower is:
(a) 149 m
(b) 156 m
(c) 173 m
(d) 200 m
Ans: (c) 173 m
Sol:
Let AB be the tower and P be the point on the ground.
tan 30° = AB / AP = 1 / √3
AP = AB × √3 = 100 × 1.73 = 173 m
