Correct Answer: (c) Rs. 720 
Solution:

Number of flats on 2nd floor of building P = 16
Number of flats on 2nd floor of building R = 14

Required ratio = 16:14 = 8:7

54. Profit earned on item C is what percentage more or less than the profit earned on item D?

Correct Answer: (b) 125% 
Solution:

Required percentage = (720 - 320)/320 × 100 = 125%

55. Directions [55-59]: Read the data carefully and answer the following questions.

There are 3 buildings P, Q and R. Each building has 3 floors, and each floor of each building has different number of flats. In building P, total number of flats is 46 and number of flats on 3rd floor is 10, which is half of that on 1st floor and also equal to that on 3rd floor of building Q. In building Q number of flats on 2nd floor is 10 less than that on 1st floor and also 1 less than that on 2nd floor of building P. In building R, number of flats on 1st floor is 18, which is 4 and 10 more than that on 2nd and 3rd floor respectively.

Ques:  What is the total number of flats on 3rd floor of all the 3 buildings together?

Correct Answer: (b) 28 
Solution:

Total number of flats in building P = 46

Number of flats on 3rd floor of building P = 10

Number of flats on 3rd floor of building Q = 10

Number of flats on 1st floor of building P = 2 × 10 = 20

Number of flats on 2nd floor of building P
= 46 - 10 - 20 = 16

Number of flats on 2nd floor of building Q = 16 - 1 = 15

Number of flats on 1st floor of building Q = 15 + 10 = 25

Number of flats on 1st floor of building R = 18

Number of flats on 2nd floor of building R = 18 - 4 = 14

Number of flats at 3rd floor of building R = 18 - 10 = 8

Buildings | 1st floor | 2nd floor | 3rd floor
P → 20 | 16 | 10
Q → 25 | 15 | 10
R → 18 | 14 | 8

Number of flats on 3rd floor of building P = 10
Number of flats on 3rd floor of building Q = 10
Number of flats on 3rd floor of building R = 8

Required sum = 10 + 10 + 8 = 28

56. Total number of flats in building R is what percent of that in building Q?

Correct Answer: (d) 80% 
Solution:

Total number of flats in building Q = 25 + 15 + 10 = 50

Total number of flats in building R = 18 + 14 + 8 = 40

Required percentage = (40/50) × 100 = 80%

57. Find the average of number of flats on 1st floor of all the 3 buildings

Correct Answer: (c) 21 
Solution:

Number of flats on 1st floor of building P = 20
Number of flats on 1st floor of building Q = 25
Number of flats on 1st floor of building R = 18

Required average = (20 + 25 + 18)/3 = 21

58. Find the ratio of number of flats on 2nd floor of building P to that on 2nd floor of building R

Correct Answer: (c) 8:7 
Solution:

Number of flats on 2nd floor of building P = 16
Number of flats on 2nd floor of building R = 14

Required ratio = 16:14 = 8:7

59. What percent of total flats in building Q are on 2nd floor?

Correct Answer: (d) 30% 
Solution:

Total number of flats in building Q = 25 + 15 + 10 = 50

Number of flats on 2nd floor of building Q = 15

Required percentage = (15/50) × 100 = 30%

60. Directions [60-64]: Read the data carefully and answer the following questions.

A bakery sold a total of 310 pastries during five days of a week (Monday to Friday). The total number of pastries sold on Monday and Thursday together is 155. The number of pastries sold on Wednesday is 25% less than that sold on Tuesday. The average number of pastries sold on Monday and Tuesday together is 70 and the average number of pastries sold on Wednesday and Thursday together is 60.

Ques : Find the ratio of the number of pastries sold on Wednesday to the number of pastries sold on Friday.

Correct Answer: (c) 9:10 
Solution:

Given, total number of pastries sold on Monday and Thursday together = 155

Let the number of pastries sold on Monday be ‘t’.

Then, number of pastries sold on Thursday = (155 - t)

Given, number of pastries sold on Wednesday is 25% less than that sold on Tuesday.

Let the number of pastries sold on Tuesday be 4y.

Number of pastries sold on Wednesday = (3/4) × 4y = 3y

Given, average number of pastries sold on Monday and Tuesday together = 70

According to the question:
=> (t + 4y)/2 = 70
=> t + 4y = 140 ..........(1)

Given, average number of pastries sold on Wednesday and Thursday together = 60

According to the question:
=> (3y + (155 - t))/2 = 60
=> (3y + 155 - t) = 120
=> t + 120 - 3y = 155
=> t - 3y = (155 - 120) = 35 ..........(2)

Subtracting equation (2) from equation (1), we get:
=> 7y = 105
=> y = (105/7) = 15

Putting the value of (y = 15) in equation (1), we get:
=> t + (4 × 15) = 140
=> t + 60 = 140
=> t = (140 - 60) = 80

Hence, number of pastries sold on Monday = t = 80

Number of pastries sold on Tuesday = 4y = (4 × 15) = 60

Number of pastries sold on Wednesday = 3y = (3 × 15) = 45

Number of pastries sold on Thursday = (155 - 80) = 75

Total number of pastries sold on all the five days together = 310

Hence, number of pastries sold on Friday = {310 - (80 + 60 + 45 + 75)} = (310 - 260) = 50

Days | Number of pastries sold
Monday → 80
Tuesday → 60
Wednesday → 45
Thursday → 75
Friday → 50

Number of pastries sold on Wednesday = 45
Number of pastries sold on Friday = 50
Hence, required ratio = 45:50 = 9:10
