Question

If 48 men can dig a trench in 14 days,how long will 28 men take to dig a similar trench?

Answer 1

Answer:

24 days

Step-by-step explanation:

Here we use ratio

Suppose the days when men are 28=x

Mens : days

48 : 14

28 : x

48:28::14:x

As it is indirect ratio

So 48:28::x:14

48×14=28x

672=28x

X=672/28

X=24

Hence 28 workers can do in 24 days

Answer 2

Answer:

by indirect variation

48*14 = 28*x

x = (14*48)/28

= 24

therefore 24 days will be required
