## 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
