Time and Distance Based DI for IBPS PO, SBI Clerk Mains, IBPS RRB PO, NRA CET, IBPS RRB Clerk and RBI Assistant Mains Exams with Detailed Solution

Directions : Study the following bar chart carefully and answer the questions given beside.

In the following figure, the bar graph shows the speeds (in km/h) of five different ships in a river and the speed of the water (in km/h) and the line graph shows the percentage of distance (in %) travelled by all the five ships.

Note: The total distance is 3000 km.
Two friends Nitin and Mukesh decided to travel 675 km till point P in downstream. Nitin is on ship B and Mukesh is on ship D. After 510 km, Mukesh’s ship broke down but immediately he got help from Neil, who is travelling in the same direction as Mukesh and is on Ship E. 
Quantity I : Time taken by Nitin to reach point P.
Quantity II : Time taken by Mukesh to reach on point P.
» Explain it
Quantity I :

Time taken by Nitin (using ship B)

675  =  675  = 12.5 hour
39 + 15 54

Quantity II :

Time taken by Mukesh (using Ship D + Ship E)

510  +  165  = 10.01 + 3.437 = 13.447 hours
31 + 19.5 36 + 12

Here, Quantity I < Quantity II

Hence, option E is correct.
The speed of another ship, F is 11.11% more than the speed of ship C and speed of stream (for Ship F) is 25% more than the speed of stream for ship E.
Quantity I : Find the time taken by ship F to cover a distance of 2625 km in upstream direction.
Quantity II : Find the time taken by ship C to cover a distance of 1860 km in upstream direction.
» Explain it
Quantity I :

Speed of ship F = 45 × 111.11% = 50 km/hr

Speed of stream for ship F = 12 × 125% = 15 km/hr

Time taken by ship F to cover 1860 km (upstream)

2625  =  2625  = 75 hours
50 – 15 35

Quantity II :

Time taken by ship C to cover 1860 km (upstream)

1860  = 77.5 hours

Hence, option B is correct.
The total distance is increased by 25%.
Quantity I : The time taken by ship C to cover the new distance in upstream.
Quantity II : The time taken by ship A to cover old distance in downstream.
» Explain it
New Distance = 3000 × 125% = 3750 km

Quantity I:

Time taken by ship C to cover new distance (upstream)

3750 × 20%  =  750  hours
24 24

Quantity II :

Time taken by ship A to cover old distance (downstream)

750  =  125  hours
54 9

Hence, option D is correct.
Time taken by ship A and B together to travel their respective destinations in downstream is approximately ______ percent more or less than time taken by ship E to travel its destination in upstream.
» Explain it
Time taken by ship B (in downstream)

450  =  150  hour
54 18

Time taken by ship A (in downstream)

750  =  250  hour
54 18

Time taken by ship B + ship A

250  +  150  =  400  hour = 22.22 hours 
18 18 18

Time taken by ship E (in upstream)

660  =  55  hour = 27.5 hours
24 2

Time taken by ship B and A (in downstream) is percent more or less than time taken by ship E ( in upstream)

22.22 – 27.5  × 100 = – 19.2% 

Hence, option C is correct.
Quantity I : The average time taken by all the ships to cover their respective distances in upstream.
Quantity II : Time taken by ship E to travel 1728 km in still water.
» Explain it
Quantity I :

Time taken by ship A (upstream) =  750  =  125  hours
12 2

Time taken by ship B (upstream) =  450  =  75  hours
24 4

Time taken by ship C (upstream) =  600  = 25 hours

Time taken by ship D (upstream) =  540  = 45 hours

Time taken by ship E (upstream) =  660  =  55  hours
24 2

After adding all the times we get = 180.70 hours

Average Time =  180.70  = 36.14 hour

Quantity II:

Time taken by ship E to cover 1728 km in still water

1728  = 48 hours

Hence, option E is correct.
