Answer :
Let
x -----> amount saved by Helga
y ----> amount saved by Maurice
z ----> amount saved by Nora
we have that
x+y+z=60 ------> equaton A
x/y=8/3
x=(8/3)y ------> equation B
y/z=3/4
z/y=4/3
z=(4/3)y -----> equation C
substitute equation B and C to equation A
(8/3)y+y+(4/3)y=60
solve for y
(12/3)y+y=60
4y+y=60
5y=60
y=12
Find the value of x
x=(8/3)(12)=32
Find the value of z
z=((4/3)(12)=16
therefore
