Answer 1

Your Question is unclear.

If you mean - Mrs Goel is 27 years older than her daughter Rekha.After 8 years she will be twice as old as Rekha .Find their present ages.

Consider present age of rekha = x

present age of mrs. Goel = x+27

After 8 years - rekha would be x+8 and Mrs. goel would be x+27+8 = x+35

it says after 8 years Mrs goel age = 2 times Rekha s age

x+35 = 2(x+8)

x+35 = 2x + 16

solving equation = x = 19

so rekha  is 19 years and mrs. goel is 46 years
