The number of cars 20 men can assemble in one day is 70 cars

let

  • x = number of cars assembled by 20 men

8 men can assemble 28 cars in one day

20 men assemble x cars in one day

How to solve ratio equation

Number of men : Number of cars

8 : 28 = 20 : x

8/28 = 20/x

8 × x = 28 × 20

8x = 560

x = 560/8

x = 70 cars

  • 6 men can paint a building in 15 days

  • 5 men to paint the same building x days

Number of men : number of days

6 : 15 = 5 : x

6/15 = 5/x

6 × x = 15 × 5

6x = 75

x = 75/6

x = 12.5 days

Therefore, it will take 5 men to paint the same building 12.5 days
