Answer 1

Explanation:

since we have given that

7 men and 8 boys can do a piece of work in 2 days.

4men and 12 boys can do 29/56 of the work in one days.

so,by using time and work

(7m+8b) 2/1= (4m+12b)1/29/56

=>7m+8b=(4m+12b/29) 56/2

=>29(7m+8b)=28(4m+12b)

=>203m+232b=112m+336b

=>203m-112m=336b-232b

=>91m=104b

=>b=91m/104

=>b=7m/8

so,number of days one man will do this

work is given by

(7m+8b)2=(1m)x

=>(7m+(8) 7m/8) 2= (1m)x

=>(7m+7m)2=(1m)x

=>(14m)2=(1m)x

=>x= 28 days

hence ,1 man will do this work in 28 days.
