Answer:

  • Deepika - 15
  • Kanchan - 10

Step-by-step explanation:

Given an age difference of 5 years and that Deepika was twice Kanchan's age five years ago, you want their present ages.

5 years ago

The relation five years ago between Deepika's age (d) and Kanchan's age (d-5) was ...

  d = 2(d-5)

  d = 2d -10 . . . eliminate parentheses

  10 = d . . . . . . . add 10-d

  (d -5) = 10 -5 = 5

Ages now

At present, the ages are ...

  Deepika = 10 +5 = 15

  Kanchan = 5 +5 = 10

Additional comment

The age difference always remains the same, so the difference 5 years ago is the same as the difference 5 years later.
