Answer 2

Answer:

16 men can complete the work in 50 hours.

Step-by-step explanation:

Given, 40 men can do a piece of work in 20 hours

To find: number of hours required by 16 men to complete the task

Let the number of hours required by 16 men be 'x'

men (X)     40     16

hours (Y)  20      x

X1Y1 = X2Y2

40 × 20 = 16 × x

800 = 16x

$x= \frac{800}{16}$

x = 50

Therefore, 16 men can complete the work in 50 hours.
