Answer:

a. 2

b. 12

c. 15

d. See below

Explanation:

It takes 6 people 20 days to paint 4 houses [A]

More the people less for same number of houses ==> less the time
More the people working for same time ==> more the number of houses

a. 3 people working for 20 days can finish only half of 4 houses = 2 houses

b. To paint 4 houses in 10 days will require twice the manpower which is 2 x 6 = 12 people

c. For 8 people to paint 4 houses, number of days = 6/8 x 20 = 15

d

People Days Houses

6 20 4

1 120 (2 x 20) 4

1 30 ( 120/4) 1

6 60 12 (3 x 20)

4 60 8 (4/6 x 12)

Use the following info to complete the table

1 person will take 6x20 = 120 days to paint 4 houses

To paint 1 house, this time will be 1/4th = 120/4 = 30 days

So it takes 1 person 30 days to paint 1 house
