Answer:
5 days
Step-by-step explanation:
A= 12 days, B= 16 days (given)
48 units (prime factorize)
A's 1 day work = 48/12 = 4 units
B's 1 day work = 48/16 = 3 units
A+B's 1 day work = 4+3 = 7 units
A+B's 4 days work = 7*4 = 28 units
remaining work done by A = 48-28
= 20 units
therefore, A can complete the remaining work in 20/4 days = 5 days
