101. What is the ratio of the number of females who watch English TV Series from cities V and X together and the number of males who watch Spanish TV Series from cities W and U together?

Correct Answer: (c) 2 : 5 
Solution:

Required ratio = (1500 + 2100) : (4000 + 5000)
= 2 : 5

102. What is the difference between the number of males who watch English TV Series from cities V and W together and number of females who watch Spanish TV Series from cities U and X together?

Correct Answer: (d) 1400 
Solution:

Required difference = (3500 + 3300) - (3000 + 2400) = 1400

103. What is the ratio of number of males who watch English TV series from cities U and Y together to the number of females who watch Spanish TV Series from cities X and Y together?

Correct Answer: (d) 39 : 32 
Solution:Required ratio = (3000 + 4800) : (2400 + 4000)
= 39 : 32

104. If the number of males who watch Hindi TV Series from city W and X is 30% and 40% of the number of females who watch Spanish TV Series from city U and V respectively, then what is the total number of males who watch Hindi TV Series from city W and X together?

Correct Answer: (b) 2500 
Solution:

Required total = 30/100 × 3000 + 40/100 × 4000
= 2500

105. What is the average number of females who watch English TV series from cities V, X and Y together?

Correct Answer: (b) 2400 
Solution:Required average = (1500 + 2100 + 3600)/3 = 2400

106. Directions [106-109]: The following line graph gives the percentage distribution of the distances covered upstream and downstream by a boatman on 6 days of a week.

Total Upstream distance = 200 km
Total Downstream distance = 300 km

The following table gives the speed of the stream on the 6 days of the week:

Day

Speed of stream (km/h)

Sunday

-

Monday

1

Tuesday

-

Wednesday

1.5

Thursday

-

Friday

1.5

Ques: Speed of stream on Sunday was 0 km/h and time taken by boat for Upstream journey was 2 hours. Time taken for downstream journey on Friday was same as time taken for downstream journey on Sunday. What was the time taken for Upstream journey on Friday?

Correct Answer: (c) 5 hrs 
Solution:

106. (c): Upstream speed on Sunday = (Upstream distance)/(Upstream time)
= (42)/(2) = 21 km/h

Speed of stream = 0 so, Speed of boat = 21 km/h.

Downstream time taken on Sunday = (Downstream Distance)/(Downstream speed)
= (63/21) = 3 hrs.

Downstream speed on Friday = (Downstream distance)/(Downstream time)
= (33/3) = 11 km/h

So, speed of boat on Friday = 11 - 1.5 = 9.5 km/h,
Speed of boat in Upstream condition = 8 km/h

Upstream time = (Upstream Distance)/(Upstream speed)
= (40/8) = 5 hrs.

107. On Tuesday speed of boat was 11 km/h more than speed of stream on same day, and time for downstream journey on Tuesday was 3 hrs. How much time will it take for Upstream journey on Tuesday to travel double the given distance?

Correct Answer: (d) 8 hrs 
Solution:

Downstream speed on Tuesday = (Downstream distance)/(Downstream time)
= (54/3) = 18 km/h

Let speed of stream be d
As given speed of boat is 11km/h more than speed of stream

d + 11 + d = 18
d = 3.5 km/h and Speed of boat = 14.5 km/h

Upstream speed = 11 km/h
Upstream time = (2 × Upstream Distance)/(Upstream speed)
= (88/11) = 8 hours.

108. On Thursday, average speed of Upstream and Downstream journey was 15.8 km/h and time for Downstream journey was 50% more than time for Upstream journey on Thursday. What was the difference between speed of boat and speed of stream on Thursday?

Correct Answer: (e) None of these
Solution:

Average speed = (Total distance)/(Total time)

Total time = (Total distance)/(Average speed)
= (79)/(15.8) = 5 hrs.

Let Upstream time be T,
T + 1.5T = 5
T = 2 hrs.

Required difference is upstream speed.

Upstream speed on Thursday = (Upstream distance)/(Upstream time)
= (22/2) = 11 km/h

109. If on Friday, difference between Upstream and Downstream speed was 3 km/h and Speed of boat was 8 km/h more than the speed of stream, then what was the average speed of boat on Friday for Upstream and Downstream journey?

Correct Answer: (d) 9.125 km/h 
Solution:

Speed of boat = Speed of stream + 8 = 9.5 km/h

Upstream time = (Upstream Distance)/(Upstream speed)
= 40/8 = 5 hrs.

Downstream time = (Downstream Distance)/(Downstream speed)
= 33/11 = 3 hrs.

Average speed = (Total distance)/(Total time)
= (73/8) = 9.125 km/h

110. Directions [110-114]: Read the data carefully and answer the following questions.

Pie chart given below shows the degree distribution of number of male visitors in a park on six different days. Total number of male visitors in the park on all six days together = 90

Table given below shows the ratio of number of male to that of female visitors in the park.

Days

Ratio of male to female visitors

Mon

9 : 10

Tue

3 : 2

Wed

1 : 3

Thu

3 : 5

Fri

3 : 4

Sat

7 : 4

Ques : Average of total number of visitors in the park on Wed and Thu lies between:

Correct Answer: (b) 15 and 20 
Solution:

No. of male visitors in the park on Mon = 90 × (72/360) = 18
No. of female visitors in the park on Mon = 18 × (10/9) = 20
Total number of visitors in the park on Mon = 18 + 20 = 38

No. of male visitors in the park on Tue = 90 × (108/360) = 27
No. of female visitors in the park on Tue = 27 × (2/3) = 18
Total number of visitors in the park on Tue = 27 + 18 = 45

No. of male visitors in the park on Wed = 90 × (12/360) = 3

No. of female visitors in the park on Wed = 3 × (3/1) = 9
Total number of visitors in the park on Wed = 3 + 9 = 12

No. of male visitors in the park on Thu = 90 × (36/360) = 9
No. of female visitors in the park on Thu = 9 × (5/3) = 15
Total number of visitors in the park on Thu = 9 + 15 = 24

No. of male visitors in the park on Fri = 90 × (48/360) = 12
No. of female visitors in the park on Fri = 12 × (4/3) = 16
Total number of visitors in the park on Fri = 12 + 16 = 28

No. of male visitors in the park on Sat = 90 × (84/360) = 21
No. of female visitors in the park on Sat = 21 × (4/7) = 12
Total number of visitors in the park on Sat = 21 + 12 = 33

Total number of visitors in the park on Wed = 12
Total number of visitors in the park on Thu = 24
Average = (12 + 24)/2 = 18
Hence, average lies between 15 and 20.
