Question

If 18 women can reap a field in 7 days, In what time can 6 women reap the same field?
​

Answer 1

So, 1 man can do the task in 12 x 7 = 84

So, part of total work completed in one day by a man = 1/84

Work completed by 4 men in one day = 4/84 = 1/21 = 3/63

18 women can do the same task oin 7 days.

So, one woman can do task in 18 x 7 = 126

So, part of total work completed in one day by an woman = 1/126

Work completed by 8 women in 1 day= 8/126 = 4/63.

Therefore, fraction of work completed in one day by 4 men and 8 women, = 3/63 + 4/63 = 7/63 = 1/9.

So work is completed by 4 men and 8 women in 9 days.
