Solution :In 1 DAY `(6XX10)` wpmen can complete the PIECE of work
and in 1 day `(10xx15)` children can complete the same
piece of work.
`therefore 6xx10` women `equiv 10xx15`children
`rArr 2 ` women `equiv 5` children
`therefore 6` women `+ 10` children `=(15+10)` children
= 25 children
`M_(1) D_(1)=M_(2)D_(2) rArr 10xx15=25xxD_(2)`
`rArr D_(2) = (10xx15)/25=6` days
