SOLUTIONS:

Car A travels 3hrs. 3*30=90km
Difference between speeds 50-30=20km/hr
T=D/S ===>102/20=5 hrs 6 mins

Speed ratio 40:37 1/2==>40: 75/2==>80:75 ie 16:15
ratio diff  between speed is 1[16-15] 1 ===> 200 (more distance)
[16+15]31 ===>?
31*200=6200km.

He takes 40 minutes less to cycle than to walk. Thus, on the whole he takes 40 more.
Required time = 3 hours 20 minutes
The speeds of two persons is 108 kmph and 75 kmph.
The first person covers (108*10)=1080 km in 10 hours and thus he makes (1080/90)=12 rounds.
Thus, he will pass over another person 12 times in any one of the direction.
Speed of 2nd truck = [(400 + 200)/20] * [18/5] kmph  = 108 kmph
Let speeds be x km/hr and y km/hr
So 225/(x+y) = 3
And 225/(x/2 + 2y/3) = 5
Solve, x = 30, y = 45
Explanation :
Explanation :
Explanation :
L = 15*5/18*30 = 125 meter

Explanation :
Let ‘T’ and ‘P’ are the length of train and platform respectively
T = 12*30*5/18 = 100 meter
P + 100 = 45*5/18*36
P= 350

Explanation :
Distance travel by first train in one hour = 30, now the distance remains 120 km only.
x/30 = (120 – x)/20, so we get x = 72 km
Now, time = (30 + 72)/30 = 3hrs and 24minutes i.e. 9: 24 am

12.A
Let total distance = 100x

Distance covered by car = 20% of 100x = 20x

 Distance covered by Train = 5 × 50% of (100x – 20x) = 5 × 40 x = 25x 5 + 3 8

 Distance covered by Taxi = 3 × 50% of (100x – 20x) = 3 × 40 x = 15x 5 + 3 8

Distance covered on feet = 100x – 20x – 25x – 15x = 40x

Total distance covered by Car and Taxi = 20x + 15x = 35x = 126 km (Given)

 Length of journey = 100 × 126 = 360 km 35

Hence, option (A) is correct.

13.B
A beats B by 15 sec means A reaches the destination 15 sec ahead of B or B reaches 15 sec later than B.  Let all of them compete in a 2 km  or 2000 m race, now we can compare them as follows:
A beats B by 150 sec, B beats C by 100 sec, C beats D by 80 sec, D beats E by 70 sec, ⇒ E would finish the race 400 sec after A.
Now, if A has to beat E by 800 m then we can say that E will cover the remaining 800m in 400sec, and cover 2000m in 1000 sec. A has to reach 400s earlier i.e in 600 sec,
 so A’s speed = 2000 = 3.33 m/s. 600

Hence, option (B) is correct.

14.A
Let the usual duration of the flight be X hours

 Usual speed of the flight = 1800 X

 Then, 1800 – 1800 = 300 X X + 1 2

 ⇒ 1800 – 3600 = 300 X 2X + 1

⇒ X(2X + 1) = 6

⇒ 2X2 + X – 6 = 0
 ⇒ X = 3 hours 2

Hence, option (A) is correct.

15.A
Relative speed of the train with respect to the bus = 156 – 30 = 126km/h

 = 126 × 5 18

= 35m/s

Distance = 440 + 260 = 700 metre

 Required time = 700 = 20 seconds 35

Hence, option (A) is correct.
