One painter can paint the entire house in 8 hours. The rate at which the painter paints is 1/8. If three painters are painting the house the rate at which they paint the house is 3*(1/8) = 3/8.
The number of hours they need to paint the house is 8/3 hours = 2 hours 40 minutes.
The correct option is B, 2 hours and 40 minutes

B 2 hours and 40 minutes, unless they take alot of breaks, lol
one painter can paint in three hours therefore three painters can paint in 2 hours and 40 minutes
2 hours and 40 minutes
we will use ratio and proportions here :
painter : painter :: hours : hours
1 : 3 :: x : 8
1/3 = x/8
3x = 8
x = 8/3
x =2.6 hours
which is nearly equal to option B (2hours and 40min)
