Question

the ages of A:B is 5:3.after 6 years their age will be 7:5.then the present age of A is​

Answer 1

Step-by-step explanation:

Let x be the common age between A and B

Their ages are 5x and 3x respectively.

After 6 years,

Age of A=5x+6

Age of A after 6 years=7x

According to the question,

5x+6=7x

5x-7x=-6

-2x=-6

x=-6/-2

=3

Thus,

Present age of A

=5x

=5*3

=15

Answer 2

Answer:

15 years

Step-by-step explanation:

forming linear eqn

5x+6/3x+6=7/5

21x+42=25x+30

4x=12

x=3

5x=15
