Find the fraction which has the same ratio to 2/13 that 5/34 has to 7/48. | [
"230/1521",
"240/1528",
"240/1542",
"240/1547"
] | D | P : 2/13 = 5/34 : 7/48
As the product of the means is equal to the product of the extremes.
P*7/48 = 2/13 * 5/34
P*7/48 = 10/442
P = 480/3094 => P = 240/1547

The sum of the present ages of a father and his son is 57 years. Six years ago, father's age was four times the age of the son. After 6 years, son's age will be: | [
"21",
"18",
"20",
"19"
] | A | Let the present ages of son and father be x and (57 - x) years respectively.
Then, (57 - x) - 6 = 4(x - 6)
51 - x = 4x - 24
x = 15
The son's age after 6 years will be 21.

Aram’s car was fined when he gave Joe and Peter a ride, so they decided to help Aram 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 Aram pay? | [
"$28",
"$15",
"$20",
"$48"
] | C | As given Aram' 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 , Aram's pay , Total Fine (... | AquaRat_train |
