उत्तर
If B does the work in 3 days, A will do it in 1 day.
B complete the work in 24 days.
∴ A complete the same work in `24/3` = 8 days.
∴ (A + B) complete the work in `"ab"/("a" + "b")` days.
= `(24 xx 8)/(24 + 8)` days
=`(24 xx 8)/32` days
= 6 days
`(24 xx 8)/4`
They together complete the work in 6 days.
