Answer 1

YOUR ANSWER

some people can do a piece of work in =12days

number of people =X

so X number of people can do this work in 12 days

two times the number of the people =2x

so 2x people can do that work in = 2x=12

=> X=12/2=6

they can do that work in 6 days

so to the half of work for 2x people =6/2

=3 days

So to complete that work they will need 6days and to the half of the work will need 3days
