Answer 1

Answer:

15 days

Step-by-step explanation:

Given,

A can do a price of work in 12 days and B alone can do it in 16 days.

A=1/12 days

B=1/16 days

LCM of 12,16 is 48

they worked together on it for 3 days and then A left.

3/48=1/16 worked together

remaining work 1-1/16=15/16

15/16 work can be done by B in 16 days

15/16*16=15 days
