2 boys will take 5 hours

Step-by-step explanation:

Answer 2

Answer:

time taken by 2 boys is 2/3

Step-by-step explanation:

4 boys = 3 hour (to paint the wall)

2 boys = x hour

let the number of boys be y

let the hour taken be x

therefore,

x is directly proportional to y

4/3 = 2/X

( through cross multiplication )

4x = 2×3

4x = 6

x= 6/4

X = 3/2

time taken = 1/ 3/2

= 2/3...
