## Task 1 - 010731

A good milker can milk a maximum of 8 cows in one hour. With the use of a Soviet milking machine, he can milk 96 cows in 8 hours. The 150 dairy cows that the VEG Biesdorf had in 1958 could already be milked in 3 hours with the help of a milking stand. By what percentage does the labor productivity increase

a) with the use of the Soviet milking machine,

b) with the use of a milking stand?

Note: In this case, we understand labor productivity as the quotient of the number of cows and the time required to milk them.
The initial output is the milker, who milks 8 cows per hour.

a) With the Soviet milking machine, he manages 96 cows $/ 8 \mathrm{~h}=12 \mathrm{cows} / \mathrm{h}$, which is $50 \%$ more.

b) At the milking station, 150 cows $/ 3 \mathrm{~h}=50 \mathrm{cows} / \mathrm{h}$ can be milked, which is an increase to 625 \% or by 525 \% compared to the initial output.
