Question

If 30 men can reap a field in 15 days then in how many days can 20 men reap the same field (using unitary method)

Answer 1

Answer:

Step-by-step explanation:

given:12 men can reap a field in 25 days.

we have to find in how many days 20 men can reap the same field.

this is a case of inverse proportion.

So, x1y1=x2y2

12×25=20×x

300=20x

x=300/20

x=15

hence, 20men can reap the field in 15 days.

Answer 2

Answer:

here your answer.....,.

10 days

Step-by-step explanation:

atq

30/15=20/x

2=20/x

x=20/2=10
