8 members went for a dinner together. 6 of them brought Rs.30 each. The seventh person brought Rs.10 more than the average Rs. of all eight persons. The eighth person brought Rs.55. Now find the total sum of money brought by all for the dinner.

• 280 Rs.
  If Total sum of money=x, so average=x/8
  Given 6*30+[10+(x/8)]+55=x
  (1440+80+x+440)/8=x, x=280

• Let he avg be = x
  toatl of 6 persons= 30*6=180
  money bought by 7 person = x+10
  (180+55+x+10)/8=x
  on solving, Rs. 280

• Let avg be x,
  then (180+x+10+55)/8=x
  i.e , 7x=245
  x=35
  hence total money =280
