Problem: 10 women can complete a work in 7 days and 10 children take 14 days to complete the work . how many days will 8 women and 12 children take to complete the work ?
Rationale: "1 women ' s 1 day work = 1 / 70 1 child ' s 1 day work = 1 / 140 ( 8 women + 12 children ) ' s 1 day work = ( 8 / 70 + 12 / 140 ) = 1 / 5 8 women and 4 children will complete the work in 5 days . b"
annotated_formula: inverse(add(divide(8, multiply(10, 7)), divide(10, multiply(10, 14))))
