Question

Aruns age is four years more than Prashant age 4 years ago the ratio of their ages was 5:4 find their present ​

Answer 1

Answer: Arun = 24 years ; Prashant = 20 years

Step-by-step explanation:

Let Arun's present age = x years

  Prashant's age = x - 4 years

Four years ago,

Ratio of ages = 5:4

or x - 4/x - 4 - 4 = 5/4

   x - 4/x - 8 = 5/4

 4(x - 4) = 5(x - 8)

4x - 16 = 5x - 40

40 - 16 = 5x - 4x

24 = x

∴ Prashant's age = x - 4

                            = 24 - 4

                            = 20 years
