Question

A man tells tells his daughter seven years ago i was 7 times as old as you were then also 3 years from now i shall be 3 times as old as you will be find their present ages

Answer 1

Answer:

Step-by-step explanation:

Let present age of man=x

Let present age of daughter=y

Seven years ago:

Age of man=x-7

Age of daughter=y-7

Acc. to question:

x-7=7(y-7)

x-7=7y-49............(1)

Three years from now:

Age of man=x+3

Age of daughter=y+3

Acc. to question:

x+3=3(y+3)

x+3=3y+9...............(2)

Subtracting (2) from (1)

We get,

y=12

Substituting value of y in (2)

We get,

x=42

So, present age of man= 42years

And present age of daughter= 12years
