If a programmer will take to think 10 min for 100 line and take 10 min to write 100 line

t=0||think||t=10||break||t=15||write(50lines)||t=20||break||t=25||write(50lines)||t=30
So at t=30 he has completed the 100lines in 30minutes.
Rate of programmer will be 100/30=10/3 lines per minute.

he thinks 50 lines in 5min and writes 50 lines in 5min and takes 10 min rest. ie in 20 min he writes 50 lines and 1 hour 150 lines.
ans 150 lines/hour

5 min rest
10 min think
5 min rest
10 min type

for one hour programmer can write 200 lines .
10+5+10+5=30 min to write 100line program.
so,in one hour programmer can write 200 lines .

so he will write 50/(10+5)=10/3 lines per min
