Sam’s car was fined when he gave Joe and Peter a ride, so they decided to help Sam pay the fine. Joe paid $3 more than 1/4 of the fine and Peter paid $3 less than 1/3 of the fine, leaving pay $4 less than 1/2 the fine to complete the payment. What fraction of the fine did Sam pay?
A. $13
B. $15
C. $20
D. $28
E. $48
Kudos for a correct solution.I did the same way as most of the people have done. I have also solved in the following way, a little bit reverse thing, please let me know if I am doing wrong here.
As given sam' payment is [1][/2]*Fine -4
i.e Total Fine = 2 * (Sam's payment + 4)
Now, as everything looks integer, Fine should be able to divide by 4 and 3 . Because Joe's contribution has 1/4 of the fine and Peter's contribution has 1/3 of the fine
So, that leads me to following :
Options , Sam's pay , Total Fine (F) , F/4 , F/3
A) , 13 , 34 , No i.e 34/4 , No i.e 34/3
B) , 14 , 38 , No , No
C) , 20 , 48 , Yes Yes
,
No need to further go on as we have got F/4 and F/3 correct, just for confirmation we go further
D) , 28 , 64 , Yes , No
E) , 48 , 104 , Yes , No
So we can see the Option C has the correct values
