Question

24 labourers working 6 hours a day can finish a piece of work in 14 days. 5

If each labourer works 7 hours a day, find the number of labourers to

finish the same piece of work in 8 days. ​

Answer 1

Step-by-step explanation:

We know k = x/y

2.5/5 = x1/8

By cross-multiplying

8(2.5) = 5×1

20 = 5x1

x1 = 20/5

= 4

We know k = x/y

4/8 = x2/12

By cross-multiplying

12(4) = 8x2

48 = 8x2

x2 = 48/8

= 6

We know k = x/y

6/12 = 15/y1

By cross-multiplying

6y1 = 15(12)

6y1 = 180

y1 = 180/6

= 30

x 2.5 4 6 15

y 5 8 12 30
