Question

5 years ago lucky was 3 times as old as lovely 10 years later lucky would be twice as old as lovely. How old are they now

Answer 1

Answer:

Age of Lovely = 20 years

Age of Lucky = 50 years

Step-by-step explanation:

Let the current age of lovely is 'x'

Let the current age of lucky is 'y'

Five years ago lovely age was (x-5) and lucky (y-5)

as per question

y-5=3(x-5)

=> 3x-y=10 -- (i)

after 10 years lovely age will be (x+10) and lucky (y+10)

as per question

y+10=2(x+10)

=>2x-y=-10 -- (ii)

Solving the two equations

x=20; y=50

∴ Age of Lovely = 20 years

  Age of Lucky = 50 years
