a , b , c can complete a piece of work in 24,6 and 12 days respectively . working together , they will complete the same work in how many days ?
"( a + b + c ) ' s 1 day work = ( 1 / 24 ) + ( 1 / 6 ) + ( 1 / 12 ) = 7 / 24 a , b , c together will complete the work in 24 / 7 days answer is c"
inverse(add(inverse(12), add(inverse(const_3), inverse(add(add(const_4, const_4), const_1)))))
