1. The number of passengers boarding Train A at Vadodara is what percent of the number of passengers boarding Train B at Mumbai?

a) 37.03% 

b) 47.03% 

c) 27.03%

d) 47.30% 

e) None of these

a) 37.03% 

Required percentage = 100/270 × 100 = 37.03%

2. What is the difference between the speed of Train A and that of Train B?

(a) 2.73 kmph 

(b) 1.97 kmph 

(c) 3.6 kmph

(d) 2.62 kmph 

(e) 3.9 kmph

Click Here to View Answer
(a) 2.73 kmph 

 Speed of Train A = 1280 / 10:20 am – 5:00 pm

= 1280 / 17 hours 20 minutes
= 1280 x 3 / 52 = 73.84 kmph
Speed of train B = 1280 / 12:00 noon ⎯ 6:00 pm
= 1280/18 hours = 71.11 kmph
So, difference between the speed of train A and train B = 73.84 ⎯ 71.11 = 2.73 kmph

3. What is the ratio of the total passengers of Train A to that of Train B?

(a) 102 : 79 

(b) 104 : 87

(c) 103 : 87

(d) 110 : 79 

(e) 113 : 87

Click Here to View Answer
(c) 103 : 87

Total passengers in train A = 400 + 100 + 90 + 300 + 150 = 1040
Total passengers in train B = 300 + 150 + 270 + 50 + 100 = 870
So, required ratio = 1040 : 870 = 104 : 87

4. The total income of Train A is what percent of the total income of Train B?

(a) 180% 

(b) 159.51% 

(c) 123.29%

(d) 125% 

(e) 127.64%

Click Here to View Answer
(e) 127.64%

Total income of train A = (400 × 50) + (500 × 70) + (590 × 280) + (890 × 100) + (1040 × 120) = Rs.434000
Total income of train B = (300 × 120) + (450 × 100) + (620 × 280) + (670 × 70) + (770 × 50) = Rs.340000
So, required % = 434000 x 100 / 340000
= 127.64% of the total income of train B.

5. If the average speed of Train A increases by 10% then when will it reach to its destination?

(a) 7:45 am

(b) 9:45 am 

(c) 8:45 am

(d) 10:45 am

(e) 11:45 am

Click Here to View Answer
(c) 8:45 am

 If the average speed of train A increases by 10%
then its new speed = 73.84 × 110/100
= 81.22 kmph
Time taken by train A during the journey = 1280/81.22 = 15.75 hours = 15 hours 45 minutes
The time when the train will reach its destination = 5 pm + 15 hours 45 minutes = 8:45 am
