Question

a mother is four tumes as old as her son. After 4 years she will be three times as old as her son what are their present ages?​

Answer 1

Let their present ages be X and Y..

Then,

$x = y \times 4$

and,

$x + 4 = (y + 4)3$

$4y + 4 = 3y + 12$

$y = 12 - 4$

$y = 8$

then,

$x = 4 \times 8 \\ = 32$

Hence, son is 8 years old.

mother is 32 years old..

Hope it helped ❤️❤️

Answer 2

Step-by-step explanation:

Present age of mother = 4x

(Let x be age of son,the present one)

4 years hence ,

Age of mother = 4x + 4

Age of son = x + 4

3(x+4) = 4x + 4

3x + 12 = 4x + 4

12 - 4 = 4x - 3x

8 = x

Present age of son = 8

Present age of mother = 32
