• For 30 min concert total invested time
  = 30 min + 1 hour + 6h= 7hour and 30 min
  i.e for 1 hour of concert
  he will take 2*( 7hour and 30 min)= 15 hour
  i.e for 90 hour of concert he will take
  = 15*90=1350hours. ans=1350hours

• 30 min= 1/2 hour
  for 1/2 an hr concert total time taken by poet(writing and rehersal)is 7hrs...(1/2=7)
  for 90hrs concert time taken = x......(90=x)
  so
  (1/2)/90=7/x
  x/2=7*90
  x=7*90*2
  x=1260

• for 30 min it is 7hrs
  for 90 hrs so 90*60=5400 min how many hrs so 5400*7/30 =1260 hrs

• for concert he take 30 mins
  number of concerts=90*(60/30)=180
  for every concert he spends 7(6+1)hours
  hence total time=180*7=1260 hours

• 1350 hours.
  
  For writing the poem he takes twice the time of the concert. So 90*2=180 hrs.
  For rehearsing, he takes 12 times the time of the concert, i.e., 12*90=1080.
  
  Hence total time = 90+180+1080=1350.

• assume
  30 min as 1 part, 1 hr has 2 parts
  and 90 hrs has 180 parts.
  then 1---->7
  180------>?
  i.e 180*7=1260 hrs.

• A poetry concert for 30 mins=(6+1)=7 hrs.
  For 90 hrs=?
  convert hrs into minutes.that is 90*60=5400 minutes.there 180 30 minutes in this 5400 mins..so 180*7=1260 hrs
