Question

# If $$a=bx,b=cy$$ and $$c=az,$$ then the value of $$xyz$$ is equal to

A
1
B
4
C
3
D
6

Solution

## The correct option is A $$1$$We have,$$a = bx$$$$b = cy$$$$c= az$$$$x = \dfrac{a}{b}$$$$y = \dfrac{b}{c}$$$$z = \dfrac{c}{a}$$Therefore,$$xyz = a/b × b/c × c/a = 1$$Hence, this is the answer.Maths
