Amount of work done by 20 men = 24 women = 40 boys

i.e 5man = 6 woman = 10 boys. -----------------(i)

According to the 1st condition, 5 men can do a job in 12 days working for 8 hours a day.

Required :- how many more men are required to work with 6 women and 2 boys.

Let the required number of men be M.

According to the given information,

=>(5 x 12 x 8 )/1=[(M + 5 + 1) x 5 x 12 ]/4. ( 6 women= 5men & 2 boys =1 men)

=>32= M + 6.

=>M=26.

Hence, 26 men are working with 6 women and 2 boys.
