Question 1 of 10

1. Question

1 points

Category: Quantitative Aptitude

Directions (Q1- 5). The efficiencies of six workers i.e. A, B, C, D, E and F were calculated by using a formula which is represented by a line graph given below. The table given below shows the number of days they work in a month (all of them do different works). Few values are missing in the table.

For the same amount of work, B earns double the money than that of F. If the monthly salary of B is Rs 18000, what is the monthly salary of F?

Correct

Answer- 3) Rs 6300
Explanation-
Ratio of work done by B and F in a month = 12 × 25/(14 × 15) = 10:7
F will be paid Rs 9000 if he does the same amount of work as B.
Monthly salary of B = 9000/10 × 7 = Rs 6300

Incorrect

Answer- 3) Rs 6300
Explanation-
Ratio of work done by B and F in a month = 12 × 25/(14 × 15) = 10:7
F will be paid Rs 9000 if he does the same amount of work as B.
Monthly salary of B = 9000/10 × 7 = Rs 6300

Directions (Q1- 5). The efficiencies of six workers i.e. A, B, C, D, E and F were calculated by using a formula which is represented by a line graph given below. The table given below shows the number of days they work in a month (all of them do different works). Few values are missing in the table.

How many days will be taken by C to finish a work which is triple of the work he does in a month and for which he works with half of his original efficiency?

Correct

Answer- 2) 108 days
Explanation-
Let the number of days taken by him to complete this work are x. Then, according to question we have,
x × 9.5/3 = 19 × 18, x = 36 × 3 = 108 days

Incorrect

Answer- 2) 108 days
Explanation-
Let the number of days taken by him to complete this work are x. Then, according to question we have,
x × 9.5/3 = 19 × 18, x = 36 × 3 = 108 days

Directions (Q1- 5). The efficiencies of six workers i.e. A, B, C, D, E and F were calculated by using a formula which is represented by a line graph given below. The table given below shows the number of days they work in a month (all of them do different works). Few values are missing in the table.

A works for x number of days in a month and D works for (x + 1) days. The monthly salary of A is Rs 31200 and that of D is Rs 10800. However, A is paid 1.6 times of the money paid to D for the same amount of work. What is the value of x?

Correct

Answer- 1) 26
Explanation-
Ratio of amount of work done by A to that of D = 31200/1.6/10800 = 65:36
We have,( 15 × x)/[8 × (x + 1)]= 65/36
We have, 108x = 104x + 104, 4x = 104, x = 26

Incorrect

Answer- 1) 26
Explanation-
Ratio of amount of work done by A to that of D = 31200/1.6/10800 = 65:36
We have,( 15 × x)/[8 × (x + 1)]= 65/36
We have, 108x = 104x + 104, 4x = 104, x = 26

Directions (Q1- 5). The efficiencies of six workers i.e. A, B, C, D, E and F were calculated by using a formula which is represented by a line graph given below. The table given below shows the number of days they work in a month (all of them do different works). Few values are missing in the table.

A, B and E together can do a piece of work in 240 days. The number of days will E take to do the same work alone are:

Correct

Answer- 3) 564
Explanation-
The efficiencies of A, B and E are in ratio 15:12:20. Therefore, the number of days taken by A, B and E will be in ratio 4:5:3
Let the number of days taken by A, B and E to complete this work are 4x, 5x and 3x respectively.
Then, 1/4x + 1/5x + 1/3x = 1/240
(15 + 12 + 20)/60x = 1/240
47/x = 1/4 , x = 188
3x = 564

Directions (Q1- 5). The efficiencies of six workers i.e. A, B, C, D, E and F were calculated by using a formula which is represented by a line graph given below. The table given below shows the number of days they work in a month (all of them do different works). Few values are missing in the table.

Number of days taken by A to complete the same amount of work as done by E in a month are 24. The number of days for which E works in a month are how much percent less than that of B?

Correct

Answer- 5) 28%
Explanation-
Let the number of days for which E works in a month are x.
Efficiencies of A and E are 15 and 20. Then,
15 × 24 = 20 × x
We have, x = 18
Required percentage = (25 – 18)/25 × 100 = 7 × 4 = 28%

Incorrect

Answer- 5) 28%
Explanation-
Let the number of days for which E works in a month are x.
Efficiencies of A and E are 15 and 20. Then,
15 × 24 = 20 × x
We have, x = 18
Required percentage = (25 – 18)/25 × 100 = 7 × 4 = 28%

Directions (Q6-10). There’re three teachers in a prestigious coaching institute i.e. Suresh, Kishore and Anand. They work for only 5 days. They take different number of classes on every day of the weak as shown by the following table. Few values are missing in the table. There’s another table which shows the amount of money they are paid for each class.

Amount of money paid to all the three teachers together on Wednesday is Rs 38000 and that on Tuesday is Rs 32200. The number of classes taken by Kishore in a week are how much more than that of Suresh?

Correct

Answer- 2) 8
Explanation-
Let the number of classes taken by Kishore on Wednesday are x and that on Tuesday are y. Then,
2 × 3500 + x × 4700 + 1 × 2800 = 38000
7000 + 4700x + 2800 = 38000
4700x = 28200, x = 6
Also, 6 × 3500 + y × 4700 + 4 × 2800 = 32200
4700y = 32200 – 21000 – 11200 = 0
Therefore, y = 0
Total number of classes taken by Kishore in a week = 5 + 0 + 6 + 3 + 5 = 19
Total number of classes taken by Suresh in a week = 3 + 6 + 2 + 0 + 0 = 11
Required difference = 19 – 11 = 8

Incorrect

Answer- 2) 8
Explanation-
Let the number of classes taken by Kishore on Wednesday are x and that on Tuesday are y. Then,
2 × 3500 + x × 4700 + 1 × 2800 = 38000
7000 + 4700x + 2800 = 38000
4700x = 28200, x = 6
Also, 6 × 3500 + y × 4700 + 4 × 2800 = 32200
4700y = 32200 – 21000 – 11200 = 0
Therefore, y = 0
Total number of classes taken by Kishore in a week = 5 + 0 + 6 + 3 + 5 = 19
Total number of classes taken by Suresh in a week = 3 + 6 + 2 + 0 + 0 = 11
Required difference = 19 – 11 = 8
