Anna is 5 years older than Beth. In 5 years, the product of their ages will be 1.5 times the product of their present ages. How old is Beth now

Question

 please help me.needed so much sir

Answer 1

Let x = Beth's age now

 

Then, x+5 = Anna's age now

 

Beth's age in 5 years = x+5

 

Anna's age in 5 years = (x+5)+5 = x+10

 

So, (x+5)(x+10) = 1.5x(x+5)

 

               x+10 = 1.5x

 

                   10 = 0.5x      x = 20
