Question

30 men can harvest a field in 14 days ,find the time taken by 20 men for the same job?

Answer 1

Heya mate,Here is ur answer

Time taken by 30 men to harvest a field = 14 days.

$<b><u>We know that</u></b>$




$<b>Work is indirectly proportional to the men.</b>$




$<b>#When men are decrease, number of days for finishing the work will increase.</b>$




So, we will multiply.

Time taken by 30 men = 14 days

Time taken by 1 men =30×14 days

Time taken by 20 men =
$\frac{30 \times 14}{20}$


$= 3 \times 7$


$= 21 \: days$


$<b>So, time taken by 20 men to finish the work = 21 days.</b>$

Answer 2

ANSWER :)

●No. of days required by 30 men to harvest a field = 14 days

●No. of days required by 1 man to harvest a field
= 30 × 14 = 420 days

☆NOTE☆
THIS IS A QUESTION OF INVERSE VARIATION.
So, More men less days and Less men more days.

Therefore,
No. of days required by 20 men to harvest a field =
420 / 20
21 days

● Your answer is 21 days

Hope this helps....
