Answer 1

Answer:

12 more men

Step-by-step explanation:

Given,

A field can be cleared by 33 men in 15 days

we know,

men*hours*days=work

33*15=work   ----(1)

How many more men will be required if the field has to be cleared

4 days earlier?​

let x be extra men required to complete work in 4 days earlier means

(33+x)*(15-4)

(33+x)*11=work   ----(2)

let us equal Equations

33*15=(33+x)*11

45=33+x

x=12 extra men
