Question

40 men can finish a piece of work in 26 days.How many men will be required to finish the work in 16 days?

Answer 1

40 multipication 16 and then divide into 26 you will get answer

Answer 2

Given:

40 men finish work in 26 days.

To find:

No. of men required to finish the same work in 16 days.

Solution:

Here we can make the following chart since the work to be finished is same in both the cases.

No. of men || No. of Days
||
1) 40 || 26
2) x || 16


Here we have taken 'x' as we don't know the no. of men in the second case.

Now using Inverse Proportion formula, as if the no. of men will increase the time will decrease.

$40 \times 26 = x \times 16$
$1040 = x \times 16$
$x = 1040 \div 16$
$x = 65$
Hence, the required no. of men will be 65 to finish the work in 16 days.

Hope you have understood the answer....
