THIS IS YOUR ANSWER MY FRIEND

Answer 2

Here it is given that 6 men can do a piece of work in 6 days

We have to find out the number of days 3 men will take to complete the same work

So, let the number of days be x

We will use inverse proportion

number of days 6 men take = 6

number of days 3 men take = x

6 ×6 = 3 × x

36 = 3x

x = 36/3

x = 12

Hence, 3 men will take 12 days to complete the work
