DAYS NEEDED BY 25 WORKERS = 20

DAYS NEEDED BY 1 WORKER = 20 * 25

= 500.

DAYS NEEDED BY ( 25 - 5 ) WORKERS = 500 / 20

= 25.

Answer 2

Answer:

25 days

Step-by-step explanation:

this is a inverse proportion so

no. of workers 25     20

no. of days       20       x

25/20=20/x

therefore

25*20=20*x

500=20x

500/20=x

25=x

hence 25 days are required
