Answer 2

Answer:

Total work =32×20= 640 unit

80% is done

that means only 20% is to be done in next 8 days

20% of 640 =

$640 \times \frac{20}{100} \\ = 128 \: unit$

no. of people need to be removed=

$= > \frac{128}{32 - x} = 8 \\ = > \frac{128}{8} = 32 - x \\ = > 16 = 32 - x \\ = > x = 32 - 16 = 16$

hence 16 men are to be removed so that the worl can finished on time
