Question

4 men can build a wall in a 12 days. Working at the same rate, how long would it take 6 men to build the wall?

Answer 1

Answer:

this is a case of inverse proportion

Formula is x1×y1=x2×y2

4×12=6×y2

y2=4×12/6=8 days

Answer 2

Answer:

4 men's build a wall in 12days

wall build= no° of men × no°of days

=48m

days to build the wall= 48= 6 × y

y= 8 days

Step-by-step explanation:

wall build= 4×12

=48 m

step 1 48 = 6× y

step 2 48/6 = y

step 3 =8 days

That means 6 mens takes 8 days to complete the wall at same rate.
