Question

The sum of the ages of Frank and Dana is 76 years. 6 years ago, Frank's age was 3 times Dana's age. How old is Frank now?

Answer 1

Answer:

Sum of ages of lara and frank

before 6 years = 76 - 6 = 70

Let Frank age be 3x

let Lara age be x

therefore, 3x + x = 70

3x + x = 70

4x = 70

x = 70 / 4

x = 17.5

age of frank now = 17.5 × 3 + 6 = 58.5 years

so lara' s age = 17.5 years

and frank' s age = 58.5 years
