Question

18 women can complete a work in12 days and 12man can complete the same work in 9days in how many days will 8man and 8women complete that work

Answer 1

Hey, Here is your Answer !

Work done by one man =12*9 = 108 days

work done in one day by one man= 1/108 days.

Work done by one woman=18*12=216 days.

work done by one woman in one day= 1/216 days.

If 8 men and 8 women work together, then,

$\frac{8}{108} + \frac{8}{216} = \frac{16 + 8}{216} = \frac{24}{216} = \frac{1}{9 \:} \: days$

8 men and 8 women together do their work in 9 days. ( Inverse Proportion)
