Answer 1

Answer:

33 men are required to complete work in 35days

Answer 2

Answer:

30 men were required to complete the work in 35 days.

Step-by-step explanation:

Given: 25 men can complete work in 42 days.

To find: Total number of men required to complete the work in 35 days

Formula used: $M_{1} D_{1} = M_{2} D_{2}$

Solution:

Given that

25 men can complete a work in 42 days.

The number of men doing a work and the number of days taken is in inverse proportion.

We have to find how many men are required to complete the work in 35 days.

Let us take

Number of men $M_{1} = 25$

Number of days $D_{1} = 42$ days

$M_{2} = ?$

$D_{2} = 35$ days

According to the given condition,

$M_{1} D_{1} = M_{2} D_{2}$

25 × 42 = $M_{2}$ × 35

1050 = $M_{2}$ × 35

$M_{2} = \frac{1050}{35}$

$M_{2} = 30$

30 men are required to complete 35 days.

Final answer:

30 men were required to complete the work in 35 days.
