Question 1153772
<br>
The algebraic solutions from the other tutors are fine; and you should know how to do them.<br>
But if an algebraic solution is not required, then solving the problem using logical reasoning and simple arithmetic can be good mental exercise.<br>
(1) Add 3 to Jordan's age so that he is EXACTLY twice as old as his cousin; that makes the sum of their ages 48+3 = 51.
(2) Divide the total 51 into two parts in the ratio 2:1 to get 34 and 17.
(3) Subtract off the "extra" 3 years you added to Jordan's age to get their real ages of 31 and 17.<br>
