Answers:
Direction (1-5)
1) Answer: c)
Upstream speed of Sumita on Monday = 16 – 2 = 14 km/h
Time taken by Sumita to travel 210 km upstream on Monday = 210/14 = 15 hours
Downstream speed of Suman on Monday = 18 + 2 = 20 km/h
Time taken by Suman to travel 210 km downstream on Monday = 210/20 = 10.5 hours
Required percentage = 15/10.5 x 100 = 142.8 %= 143%
2). Answer: a)
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
3). Answer: a)
Downstream speed of Sunita 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
4). Answer: c)
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 6 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%
5). Answer: c)
Downstream speed of Sumita on:
Sunday = (14 + 4) = 18 km/h
Monday = (16 + 2) = 18 km/h
Tuesday = (12 + 6) = 18 km/h
Wednesday = (10 + 3) = 13 km/h
Thursday = (8 + 2) = 10 km/h
Friday = (6 + 4) = 10 km/h
Saturday = (12 + 5) = 17 km/h
Required sum of the times = 160/18 + 160/18 + 160/18 + 160/13 + 160/10 + 160/10 + 160/17
= 8.88 + 8.88 + 8.88 + 12.30 + 16 + 16 + 9.41
= 80.35 hours
Direction (6-10)
6). Answer: d)
Number of days taken by Monu to complete the work = 6/5 x 15 = 18 hours
Number of days taken by Bonu to complete the work = 7/10 x 20 = 14 hours
Let the number of days taken by Anu, Ranu, Monu and Bonu together to complete the work = x
x(1/12 + 1/18 + 1/18 + 1/14) = 1
=>x(21 + 14 + 14 + 18)/252 = 1
=> x = 252/67
=> x = 3(51/67) days
7). Answer: a)
Number of days taken by Anu and Renu together to complete the work = (12 x 15)/(12 + 15)
= 180/27
= 20/3
Number of days taken by Tanu and Ranu together to complete the work = (20 x 18)/(20 + 18)
= 360/38
= 180/19
Efficiency ratio:
(Anu + Renu): (Tanu + Ranu) = 3/20: 19/180 = 27:19
Required percentage = 27/19 x 100 = 142.105%
8). Answer: b)
Number of days taken by Sonu to complete the work = ¾ x 12 = 9 days
Number of days taken by Monu to complete the work = 6/5 x 15 = 18 days
Number of days taken by Bonu to complete the work = 7/10 x 20 = 14 days
Number of days taken by Tonu to complete the work = 8/9 x 18 = 16 days
Number of days taken by Sonu and Monu together to complete the work = (9 x 18)/(9 + 18)
= (9 x 18)/27
= 6 days
Number of days taken by Bonu and Tonu together to complete the work = (14 x 16)/(14 + 16)
= (14 x 16)/30
= 112/15 days
Required ratio = 6 : 112/15
= 90:112
= 45:56
9). Answer: d)
Number of days taken by Tonu to complete the work = 8/9 x 18 = 16 days
Number of days taken by Tinu to complete the work = 5/8 x 16 = 10 days
Let the number of days taken by Tonu and Tinu together to complete the work = x
5/15 + 5/16 + x(1/16 + 1/10) = 1
=>x(5 + 8)/80 = 1 – 1/3 – 5/16
=> 13x/80 = (48 – 16 – 15)/48
=> 13x/80 = 17/48
=> x = 17/48 x 80/13
=> x = 85/39 days
10). Answer: d)
Number of days taken by Sonu to complete the work = ¾ x 12 = 9 days
Number of days taken by Monu to complete the work = 6/5 x 15 = 18 days
Number of days taken by Bonu to complete the work = 7/10 x 20 = 14 days
Number of days taken by Tonu to complete the work = 8/9 x 18 = 16 days
Number of days taken by Tinu to complete the work = 5/8 x 16 = 10 days
Let the required number of days = x
x(1/9 + 1/18 + 1/14 + 1/16 + 1/10) = 1
=>x(560 + 280 + 360 + 315 + 504)/5040 = 1
=> x = 5040/2019
=> x = 2(1002/2019) days
