If 35 labourers dig 805 cm³ of earth in 5 hours, how much of the earth will 30 labourers dig in 6 hours?
Solution:
According to given conditions, As the number of labourers decrease, the earth dug will also decrease. It is a direct proportion.
As the working time increase, the earth dug will also increase. It is also a direct proportion. Let the earth dug be x cm³
Here the equation will be
`\frac{x}{805}` = `\frac{6}{5}` x `\frac{30}{35}`
Or
x = `\frac{6}{5}` x `\frac{30}{35}` x 805 cm³
by simplifying we get
x = 828 cm³
Thus, 828 cm³ earth will be dug
