Question

if a toy company is required 36 machines to produce car toys in 54 days How many machines would be required to produce the same number of toy cars in 81 days


IS THIS INVERSE OR DIRECT ​

Answer 1

As the number of machines increases number of days required decreases.

∴ They are in inverse proportion x1y1 = x2y2

36 x 54 = x (x) 81

x= 36×54/81

x=24

∴ 24 machines would be required.
