a and b can do a piece of work in 4 2 / 3 days and 5 days respectively . they work together for 1 days and then a leaves . in how many days after that b will complete the work alone .
3 / 14 * 1 + ( 1 + x ) / 5 = 1 x = 2.92 days answer : e
multiply(5, subtract(const_1, add(inverse(5), inverse(add(const_4, divide(const_2, const_3))))))
