Charly was about to see Maria and ask for her hand in marriage, when he met Maria's little brother. The latter told him:

Five years ago, my sister was five times as old as me; now, she's only three times as old as me.

How old is Maria ?

Let x be her little brother's age....so Maria's age now is 3x

 

And we're told that

 

5(x-5) = 3x - 5     simplify

 

5x - 25  = 3x - 5    add 25 to both sides and subtract 3x from both sides

 

2x  = 20         divide both sides by 2

 

x = 10.....and that's the age of her brother, now

 

So.....Maria's age now  = 3(10) = 30
