15 programar 3 days work=1

1 programar 1 day work=1/(3*15)=1/45
15 programar 1 day work=15/45=1/3

remainder work=2/3
9 programar 1 day work=9/45=1/5
so,
9 programar 1/5 work= 1day
9 programar 1 work=5day
2/3work=5*2/3
=3.3days=4days
hence ans is 4 days

sooorryyyy guyzz.....
The best answer is c.
The total working days for finishing a web page are (15 x 3) 45. If after one day 9
programmers quit, only 15 working days are done and the rest of the programmers (6)
Need to finish (45 – 15) 30 days of work. It will take them 5 more days.

15 workers complete in 3 days..
so man*day=constant
15*3=45 man.day
now 1 day and 15 workers so
1*15=15 man.day
so left man day 45-15=30 man.day
now 6 man left so,
6 man*day=30 man*day=5 days
now total days 5+1=6 days
ans=6
