Answer 1

Answer:

30 years will be the age of A and

B and 9 years big than B

Answer 2

Present age of A is 48 years and that of B is 39 years.

Step-by-step explanation:

Let the present age of A is x years and that of B is y years.

From the give directions, the first equation is

$(x+10)=2(y-10)\\\\x+10=2y-20\\\\x=2y-30...(i)$

Now, the second condition is A is 9 years older than B.

x = 9 + y

Substituting the value of x in (i)

$9+y=2y-30\\\\2y-y=9+30\\\\y=39$

Thus, the value of x is

x = 9 + 39

x = 48

Thus, present age of A is 48 years and that of B is 39 years.
