Variation Worksheet Solution2





In this page variation worksheet solution2 we are going to see solution of practice questions from the worksheet variation worksheet.

Question 4

If 8 workers can complete a work in 24 days, then 24 workers can complete
the same work in

Solution:

Let "x" be the number of days taken

             Number of workers                       Number of days

                     8                                           24 days 

                    24                                                x

Since the number of workers increases the number of days taken to complete the work will be automatically reduces. So it is in inverse variation.

                  8 x 24 = 24 x x

                       X = (8 x 24)/24

                       x = 8 days

(1) 8 days 

(2) 16 days

(3) 12 days 

(4) 24 days  


Question 5

If 18 men can do a work in 20 days, then 24 men can do this work in

Solution:

Let "x" be the number of days taken

             Number of workers                       Number of days

                    18                                           20 days 

                    24                                                x

Since the number of workers increases the number of days taken to complete the work will be automatically reduces. So it is in inverse variation.

                  18 x 20 = 24 x x

                       X = (18 x 20)/24

                       X = 360/24

                       x = 15 days

(1) 20 days 

(2) 22 days

(3) 21 days 

(4) 15 days 


Question 6

A marriage party of 300 people require 60 kg of vegetables. What is the
requirement if 500 people turn up for the marriage?

Solution:

Let "x" be the required quantity of vegetable

             Number of people                       Quantity of vegetable

                   300                                           60 kg

                   500                                               x

Since the number of workers increase the number of days taken to complete the work will increase. So it is in direct variation.

                  300 x x = 500 x 60

                       X = (500 x 60)/300

                       X = 30000/300

                       x = 100 kg

(1) 20 kg 

(2) 15 kg

(3) 45 kg

(4) 100 kg
