Answer:
Step-by-step explanatio
p complete work in =15 days.
Q complete work in =10 days
LCM of 15&10 is 30c
So p efficiency is 2c
Q efficiency is 3c
2+3=5c
Q left after 2 days so p and q work together for 2 days so 5c*2=10c
Remaining work =30c-10c=20c
Remaining work finished by p in 20c/2c=10 days
Total work done in 10+2 =12 days.
