Question

if 20 men can build a wall in 15 days in how many days 8 men can build? is it direct proportion or inverse proportion​

Answer 1

Step-by-step explanation:

number of men × days = number of men' × days

20×15=8×X

300=8X

x=300/8

X= 37.5

this is direct proportion

OR

20/15=8/x

20×X=15×8

20X=120

X=120/20

X=6
