Answers:
Directions (Q. 1 – 5):
Q1. Answer: c
Upstream speed of Sumita on Monday = 14 – 4 = 10 km/h
Time taken by Sumita to travel 210 km upstream on Monday = 200/10 = 21 hours
Downstream speed of Suman on Monday = 16 + 4 = 20 km/h
Time taken by Suman to travel 210 km downstream on Monday = 210/20 = 21/2 hours
Required percentage = [21/(21/2)] x 100 = [21*2/21]*100 = 200%
Upstream speed of Sumita on:
Sunday = (14 – 4) = 10 km/h
Monday = (16 – 2) = 14 km/h
Tuesday = (12 – 6) = 6 km/h
Downstream speed of Suman on:
Sunday = (16 + 4) = 20 km/h
Monday = (18 + 2) = 20 km/h
Tuesday = (14 + 6) = 20 km/h
Upstream distance travelled by Sumita in 9 hours on Sunday, Monday and Tuesday together
= 10 x 9 + 14 x 9 + 6 x 9
= 90 + 126 + 54
= 270 km
Downstream distance travelled by Suman in 8 hours on Sunday, Monday and Tuesday together
= 20 x 8 + 20 x 8 + 20 x 8
= 160 + 160 + 160
= 480 km
Required difference = 480 – 270 = 210 km
Downstream speed of Sumita on:
Wednesday = 10 + 3 = 13 km/h
Thursday = 8 + 2 = 10 km/h
Sum of downstream speeds of Sumita on Wednesday and Thursday = 13 + 10 = 23 km/h
Upstream speed of Suman on:
Friday = 20 – 4 = 16 km/h
Saturday = 8 – 5 = 3 km/h
Sum of upstream speeds of Suman on Friday and Saturday = 16 + 3 = 19 km/h
Required ratio = 23:19
Upstream speed of Sumita on:
Sunday = (14 – 4) = 10 km/h
Monday = (16 – 2) = 14 km/h
Tuesday = (12 – 6) = 6 km/h
Wednesday = (10 – 3) = 7 km/h
Thursday = (8 – 2) = 6 km/h
Friday = (6 – 4) = 2 km/h
Saturday = (12 – 5) = 7 km/h
Upstream distance travelled by Sunita in 5 hours in all the days together
= 10 x 5 + 14 x 5 + 6 x 5 + 7 x 5 + 6 x 5 + 2 x 5 + 7 x 5
= 50 + 70 + 30 + 35 + 30 + 10 + 35
= 260 km
Upstream speed of Suman on:
Sunday = (16 – 4) = 12 km/h
Monday = (18 – 2) = 16 km/h
Tuesday = (14 – 6) = 8 km/h
Wednesday = (10 – 3) = 7 km/h
Thursday = (12 – 2) = 10 km/h
Friday = (20 – 4) = 16 km/h
Saturday = (8 – 5) = 3 km/h
Upstream distance travelled by Suman in 3 hours in all the days together
= 12 x 3 + 16 x 3 + 8 x 3 + 7 x 3 + 10 x 3 + 16 x 3 + 3 x 3
= 36 + 48 + 24 + 21 + 30 + 48 + 9
= 216 km
Required percentage = (260/216) x 100 = 120.37% = 120 %
Downstream speed of Sumita on:
Sunday = (14 + 4) = 18 km/h
Tuesday = (12 + 6) = 18 km/h
Friday = (6 + 4) = 10 km/h
Required sum of the time = 360/18 + 360/18 + 360/10
= > 20 + 20 + 36
= > 76 hours
Directions (Q. 6 – 10)
let C takes X hours to fill the cistern.
According to the question:
4/24 + 4/x + 5/x + 5/30 = 1
=> 1/6 + 9/x + 1/6 = 1
=> 2/6 + 9/x = 1
=> 1/3 + 9/x = 1
=> 9/x = 1-1/3
=> 9/x = 2/3
=> x = 27/2 hours
Hence, C can alone fill the cistern in 27/2 hours.
let D should be closed after x hours.
x/30 + x/45 + 20/45 = 1
=> (3x+2x)/90 = 1-20/45
=> 5x/90 = (45-20)/45
=> x/18 = 25/45
=> x = 10 hours.
Hence, D should be closed after 10 hours.
Let time taken by B to fill the cistern = 4x hours
Hence, time taken by F to fill the cistern = 2x hours
And time taken by C to fill the cistern = x hours
According to the question:
48/x + 48/2x + 48/4x = 1
=> (192 + 96 + 48)/4x = 1
=> 4x = 336
=> x = 336/4
=> x = 84 hours.
Hence, time taken by F to fill the cistern = 2 x 84 = 168 hours.
part of the tank filled in 2 hours = 1/24 + 1/30 = 9/120
=>part of the tank filled in 2 x 13 hours = 9 x 13/120 = 117/120
Remaining part = 1 – 117/120 = 3/120
Since A is opened first, time taken by A to fill 3/120 part:
x/24 = 3/120
=> x = 3/5
Hence total time = 2 x 13 + 3/5 = 26(3/5) hours.
let both the pipes can fill the cistern in x hours.
According to the question:
x/12 + x/(24 * 3) = 1
=> x/12 + x/72 = 1
=> (6x + x)/72 = 1
=> 7x/72 = 1
=> x = 72/7 hours.
Hence, both the pipes can fill the cistern in 72/7 hours.
