Question

a says to B I am thrice as old as you were when I was as old as you are the sum of their present age is 75 years find the present age of a​

Answer 1

Answer:

present age of A is 45 years and that of B is 30 years!

Step-by-step explanation:

Let the present age of B be x then present age of A will be 75-x

let y be the years before which the age of A was equal to the present age of B, therefore

75-x-y = x

y = 75-2x

Now according to the given relation,

75-x = 3[x-(75-2x)]

75-x = 3[x-75+2x]

75-x = 3 [3x-75]

75-x = 9x -225

-x-9x = -225 -75

10x = 300

x=30

So finally we've got the present age of B which is 30 years

and the present age of A is 75-30 = 45 years
