a alone can do a piece of work in 6 days and b alone in 8 days . a and b undertook to do it for rs . 3200 . with the help of c , they completed the work in 3 days . how much is to be paid to c
"explanation : c ' s 1 day ' s work = 1 / 3 − ( 1 / 6 + 1 / 8 ) = ( 1 / 3 − 7 / 24 ) = 1 / 24 a : b : c = 1 / 6 : 1 / 8 : 1 / 24 = 4 : 3 : 1 c ′ sshare = 1 / 8 ∗ 3200 = 400 option b"
multiply(multiply(subtract(inverse(3), add(inverse(8), inverse(6))), 3200), 3)
