• Any problem of this type can be solved by man days formulaa, M1*H1*D1/w1=M2*H2*D2/w2 where m->no of men h->no. of hours d->no. of days w->work done. so (10*10)/10=(x*60)/60
  and the answer is 10.

• Ans:10
  10 programers can type 10 lines in 10 min,hence 10 programmer can type 1 line in 1 min
  hence for 60 lines they will need 60 mins so 10 programmers is enough

• here 1 programer can complete 1/10th line in 10 min
  so in 60 min he can complete 6 lines
  therefore for 60 lines we will require 10 programer to write 60 lines
