Question

Ten years ago Rudi was a third of his age now. The next fifteen years age comparison between Marlina and Rudi's age is 3: 5. How many years will Marlena's age of 5 years to come?

Answer 1

»10 Years ago Rudi's age was 1/3 his age now.

»So, 10 years = 2/3 his age now.

»Age Rudi:

= 10: 2/3

= 10: 3/2

= 15 Years

»15 years later Marlina age: Rudi

= 3: 5

»Age Rudi 15 years later:

= 15 + 15

= 30

»5y = 30

y = 30 ÷ 5

y = 6

»Age of Marlina:

= 3y

= 3 (6)

= 18 (15 years later)

= 18 - 15

= 3 years (now)

»Age of Marlina 5 years later:

= 3 + 5

= 8 years

Sorry if there is a mistake in my answer ^_^
