Question

if 25 persons can dig a trench 36 m long in one day, then find the number of persons required to dig a trench 108 m long in one day?
​

Answer 1

Answer:

75 person

Step-by-step explanation:

36 m trench dig by 25 persons

1 m trench dig by 25/36 persons

∴ 108 m trench dig by 25 × 108/36 = 75 persons

Answer 2

Answer:

75

Step-by-step explanation:

as if 25 persons dig =36m

then 108/36=3

so it means that we have to dig 3 time the initial length

so we need 3x of the persons

means 25*3=75 people
