In a group of people solicited by a charity, 30% contributed $40 each, 45% contributed $10 each and the rest contributed $12 each. What is the percentage of the total contributed came from the people who gave $40?

a)25% b)30% c)40% d)45% e)50%

• 61.53%
  Contribution by 30% @ 40$ each= 30*40=1200
  Contribution by 45% @ 10$ each= 45*10=450
  Contribution by rest 25% @12$ each= 25*12= 300
  % of total contribution came from the people who gave 40$= 100*1200/(1200+450+300)= 2400/39 =61.53

• let total no of people is 100
  so 30% people means 30 people contribute $40 so total 1200
  45%--------------45 ------------------$10 -------- 450
  25% -------------25 ------------------$12 ---------300
  so total amount is 1950
  so for 30% people who contribute $40 ...total %ge contribution is 1200*100/1950=61.54

• Answer is option e: 50%
  30% of 40 = 12
  45% of 20 = 9
  25% of 12 = 3
  So total contribution = 12+9+3 = 24
  
  Percentage of contribution by people who gave $40 = Their contribution / Total contribution = 12/24 * 100 = 50%

• Put the information into a table.
  % of those solicited amount given (each) amount given (total)
  
  25% $20
  
  45% $10
  
  $5 $750
  We will need to add a 'number of people' column.
  % of those solicited amount given (each) amount given (total) number of people
  
  25% $20
  
  45% $10
  
  $5 $750
  Next we can work out the percentage who contributed $5.
  
  % who contributed $5 = %100 - %25 - %45 = %30
  
  And the number of people who contributed $5
  
  number of people who contributed $5 = = 150
  
  Add this new information into the table.
  % of those solicited amount given (each) amount given (total) number of people
  
  25% $20
  
  45% $10
  
  30% $5 $750 150
  30% of those solicited is 150 people then, 25% is 125 people and 45% is 225 people. Add into the table.
  % of those solicited amount given (each) amount given (total) number of people
  
  25% $20 125
  
  45% $10 225
  
  30% $5 $750 150
  From this we can work out how much money was contributed by each group of people.
  125 people contributed $20 which is, 125 × $20 = $2500
  
  225 people contributed $10 which is, 225 × $10 = $2250
  % of those solicited amount given (each) amount given (total) number of people
  
  25% $20 $2500 125
  
  45% $10 $2250 225
  
  30% $5 $750 150
  To find the total we just add the amount contributed by each group.
  Total = $2250 + $2500 + $750 = $5500
  
  Therefore, answer A is correct
