19 person went to party.13 of them spent 79 each and rest of them spent Rs 4 more than average expenditure of all 19.what was the total money spent by them?

• Rs.1536
  
  Let average expenditure be x
  Total money spend = 19x
  
  [13*79+6*(x+4)] = 19x
  1027+6x+24 = 19x
  13x = 1051
  x = 1051/13
  
  total money spend = 19x = 1536

• Ans--> 1536.07 rs
  
  13*79 + 6*(x/19+4)= x
  1027 + {6 (x +76)/19}=x
  19969 = 13 x
  
  x = 1536.07692

• let x be the avg of 19 people spent
  (13*79+6(x+4))/19=x
  1017+6x+24=19x
  1051=13x
  now totle money sent by 19 people 19*13x=1051*19
  19x=1051*19/13
  19x=1536
