Question

five years ago Agirl was 7 times as old as Bgirl, 20 yrs later Agirl will be twice as old as Bgirl what's the present age​

Answer 1

step by step explanation

Answer 2

Let there age be x

so B girls aged is x

and A girl is age 7x

20 years later A girl will be twice as old as B girl so

2(x+20)=(7x+20)

2x+40=7x+20

-7x+2x=-40+20

-5x = -20

x =-20/-5

minus sign will be cancelled

x = 20/5

x= 4
