Question

X:y:z -2:3:5 if X+Y+Z - 60 then value of z is

Answer 1

Answer:

z = 30

Step-by-step explanation:

x:y:z = 2:3:5

x + y + z = 60

6×2 + 6×3 + 6×5 = 60

12 + 18 + 30 = 60

60 = 60

Answer 2

The value of z is 30.

Step-by-step explanation:

Given:

x:y:z = 2:3:5 and x+y+z=60

Let the common ratio be a.

Then,

x=2a ,y =3a and z=5a

$= > x + y + z = 60$

$= > 2a + 3a + 5a = 60$

$= > 10a = 60$

$= > a = 6$

so,

$z = 5a$

$= > z = 5 \times 6$

$= > z = 30$

The value of z is 30.
