Question

1f 15 men can build a wall in 48 hours how many men will be required to do the same work in 30 hours?​

Answer 1

Answer:

24

Step-by-step explanation:

15 men = 48 hours

x men = 30 hours

In 48 hrs 15 men can complete the task  so when time is decreased number of men increases .

thus , it's a indirect proportion

so,

x₁ = 15 men

y₁ = 48 hours

x₂ = ?

y₂ = 30 hours

x₁ / y₁ = x₂ / y₂

x₂ = x₁  × y₁ / y₂

x₂ = 15 × 48 / 30

    = 24

required men = 24
