£20 is divided between Caroline, Sarah & Gavyn so that Caroline gets twice as much as Sarah, and Sarah gets three times as much as Gavyn. How much does Caroline get?

Respuesta :

Answer:

Caroline gets £12

Step-by-step explanation:

Let Caroline share be x

Let Sarah share be y

Let gavyn share be z

X = 2y

Y = 3z

X+ y + z = 20

X = 6z

Y = 3z

6z + 3z +z = 20

10z= 20

Z= 2

Y = 3z

Y= 3*2

Y= 6

X= 6z

X= 6*2

X= 12

Caroline gets £12
