Question

if 6 painters can paint a wall 9m long in 3days, then the number of painters required to paints 10m long wall in 5 days

Answer 1

Answer:

The number of painters is 4.

Step-by-step explanation:

We will use the proportion:

 6 painters          9 m                   3 days

↑                      ↑                  ↓

 x painters           10 m                  5 days

-----------------------------------------------------

x : 6 = 10 : 9 = 3 : 5

x * 9 * 5 = 6 * 10 * 3

45 x = 180

x = 180 : 45 = 4

Answer 2

Answer:

6:9:3

x:10:5

x*9*5=6*10*3

45x=180

x=180/45

x=4
