Priscilla is 4 times as old as her brother Sammy in 4 years she will be twice as old as Sammy how old are priscilla and Sammy now?

Answer 1

Priscilla is 8 and Sammy is 2. Let Priscilla's age now be x and Sammy's age now be y.

As now Priscilla is 4 times as old as Sammy, x=4y. (1)

4 years later

Priscilla's age is x+4 years and Sammy's Y+4 years.

As 4 years later, Priscilla is twice as old as Sammy,

(x+4)=2(y+4)

x+4=2y+8

as per (1) x=4y

4y+4=2y+8

2y=4

y=2

Sammy's age now is 2.

And as x=4y, and y=2.

x=8

Priscilla's age now is 8.

I wrote the first answer but now I realize it was confusing. Hope this explains the process.
