a can do a work in 6 days , b can do a work in 8 days and c can do it in 12 days . b left work after 5 days . for how many number of days should a and c should work together to complete the remaining work ?
"b work 1 / 8 * 5 = 5 / 8 remaining work = 1 - 5 / 8 = 3 / 8 a and c work together = 1 / 6 + 1 / 12 = 3 / 12 = 1 / 4 take remaining work is done in = 8 / 3 * 1 / 4 = 2 / 3 days answer : b"
add(divide(5, 6), divide(5, 8))
