Nine persons went to the hostel for taking their meals, 8 of them spent Rs.12 each on their meals and ninth spend Rs. 8 more then the average expenditure of all nine. What is the total money spent by them?

• Let x be the average of all 9 persons.
  Money spent by 8 persons = 8*12= Rs.96
  Money spent by ninth person = Rs.(x+8)
  Therefore, Average money spent by all 9 persons = 96+(x+8)/9=x
  104+x=9x
  x=13
  Money spent by ninth person = x+8= 13+8= Rs.21
  Therefore, Total money spent by all of them = 96+21= Rs.117

• let the average expenditure of all the nine be Rs.x
  then,
  12multiply by 8 +(x+8)=9x
  8x=104
  x=13.
  total money spent=9x
  (9multiply by 13)=Rs.117 (answer)

• let avg sum paid by all 9 persons = x
  so total payment = 9x
  and sum paid by first 8 persons = 12*8
  sum paid by 9th person = x+8
  therefore we get :
  9x=(12*8)+(x+8)
  we get x=13
  total amount = 13*9 = 117 (ans)

• 117..is right answer..

• Ans - 117
  
  Let the total money spent be Rs. x
  Avg. of 9 people = x/9
  8 of them spent Rs. 12 each so total is = 8*12=96
  9th person spent 8 more than the avg = x/9+8
  Thus, total amt. of money spent : x/9+8+96=x
  Solve the equation and you will get x= 117 .

• Let the total money spent be x
  8*12+(8+x)=9x
  96+8+x=9x
  104+x=9x
  104+x-9x=0
  104-8x=0
  104=8x
  104/8=x
  x=8
  9x=9*8=72

• 8×12+(8+x)=9x solve this ans:117
• 9 years agoHelpfull: Yes(0) No(3)
• 117
  9x = 12*8+x+8
  8x = 104
• 8 years agoHelpfull: Yes(0) No(1)
• (12*8+8+x)/8=x
• 8 years agoHelpfull: Yes(0) No(1)
• average of nine persons=(96+x+8)/9=x x=13
  so 96+13+8=117
• 8 years agoHelpfull: Yes(0) No(1)
• expenditure of 8 person =12*8=96
  expenditure of ninth person=8+(96/8)=116
• 8 years agoHelpfull: Yes(0) No(1)
• average money spent by 8 persons =12
  so money spent by 9th person =12+8=20
  total money spent=8*12+20=116

• Ninth one is paying rs 8 more this means he is paying rs 1 for each eight people.so if everyone among 8 pay rs 13 ninth one didnt need to pay rs 8 more hence answer is 12+1 =13

• (12*8)+(12+8)=116
• 8 years agoHelpfull: Yes(0) No(0)
• 96+x+8=9x;
  104=8x
  x=13
  total money=104+13=107
• 8 years agoHelpfull: Yes(0) No(0)
• (8*12)+(x+8)=9x
  So x which is the average money is 13
  Ans will be 13*9=117
• 8 years agoHelpfull: Yes(0) No(0)
• Ans 117
  x-8=(12*8+)9
  x=21
  so x+96=21+96=117

• Let the expenditure of 9 persons be x
  12*8 +(x+8) = 9x // 9th spent Rs 8 more than avg
  x=13
  Total money 9x => 9*13 = 117
  Ans. Rs.117
• 8 years agoHelpfull: Yes(0) No(0)
• (12*8)+(x+8)=9x
  on solving this....
  x=13
  therefore,total money is =9x
  9*13=117

• let the average expenditure of all the nine be Rs.x
  then,
  12multiply by 8 +(x+8)=9x
  8x=104
  x=13.
  total money spent=9x
  (9multiply by 13)=Rs.117 (answer)
