¼ of Edmund’s savings is the same as 1/6 of Rob’s savings. The difference in their savings is 1/5 of Kenny’s savings. Given that the total savings of the 3 boys is $340, how much money does Rob save?
Solution
20 units ----- $340
1 unit ----- $340 divided by 20 = $17
(Rob) 6 units ----- $17 x 6 = $102
Answer: Rob saves $102.
