Solution :`therefore` Work done by 6 WOMEN in 1 day `= 1/10`
Work done by 6 women in 6 days `= 6/10 = 3/5`
`therefore` Remaining work `= (1- 3/5)=2/5 ` which is COMPLETED
by 10 childrenin 6 days.
`therefore` Work done by 10 children in 1 day `= 2/(5xx6)= 1/15`
`therefore` Time taken in completing the work = 15 days.
Alternate Method:
Number of days required `= (6XX10)/4 = 15` days
