Problem: a can do a work in 8 days . b can do the same work in 4 days . both a & b together will finish the work and they got $ 1000 from that work . find their shares ?
Rationale: "ratio of their works a : b = 8 : 4 ratio of their wages a : b = 2 : 1 a ' s share = ( 2 / 5 ) 1000 = 400 b ' s share = ( 1 / 5 ) 1000 = 200 correct option is c"
annotated_formula: divide(multiply(8, 4), add(8, 4))
