Question

Vandana is twice as old as her son. in 4 years she will be four times as old as her son was 9 years ago. how old is each now?

Answer 1

Sorry I don't know the answer

Answer 2

Let the present age of Vandanaś son be X years and that of Vandana be 2X years

Then,
A/Q
2X + 4 = 4 * (X - 9)
=> 2X + 4 = 4X - 36
=> 2X - 4X = -36 - 4
=> -2X = -40
=> X = -40 / -2
=> X = 20

Therefore, the present age of Vandanaś
son is 20 years and that of
that of Vandana is
( 2 * 20 ) years
= 40 years
