Problem: a can do a work in 8 days . b can do the same work in 24 days . if both a & b are working together in how many days they will finish the work ?
Rationale: "a rate = 1 / 8 b rate = 1 / 24 ( a + b ) rate = ( 1 / 8 ) + ( 1 / 24 ) = 1 / 6 a & b finish the work in 6 days correct option is e"
annotated_formula: divide(multiply(8, 24), add(8, 24))
