ACCORDING TO QUESTION::--




$x \: can \: do \: a \: piece \: of \: work \: in \: p \: days \\ and \: y \: can \: do \: same \: in \: q \: days$

$1 \: day \: work \: of \: x \: will \: be = 1 \div p$
$1 \: day \: work \: of \: y \: will \: be = 1 \div q$
$total \: days \: required \: for \: x \: and \: y = 1 \div p + 1 \div q$
$= p + q \div pq$
$= pq \div p + q$
