Question

12 farmers harvest the crop in the field in 20 hours how many workers will be required to do the same work in 15 hours

Answer 1

Hi ,

****************************************

Inverse Proportion:

If two quantities x and y change

such that x × y = constant then

x and y are said to be in Inverse

Proportion.

x1 y1 = x2 y2

***"**************************************

Now ,

Number of formers (x1 ) = 12

Hours ( h1 ) = 20

x2 = ?

Hours ( h2 ) = 15

x2 × h2 = x1 × h1

x2 × 15 = 12 × 20

x2 = ( 12 × 20 )/15

x2 = 16

Therefore ,

16 formers can complete the same

work in 15 hours.

I hope this helps you.
