Question

if 120%of X =30%y y=80%z and z =a%of X then value of a is​

Answer 1

Answer:

25

Step-by-step explanation:

120% of X = 30% of y

=

$\frac{x}{y} = \frac{30}{120} = \frac{1}{4}$

Now y = 80% of z

$\frac{y}{z} = \frac{80}{100} = \frac{4}{5}$

Also z = a% of x

$\frac{z}{x} = \frac{a}{100}$

Therefore, x:y:z = 1/4 : 4/5 : a/100 = 25 : 20 : a

80% of z = 20

z = 20/80 x 100 = 25 Ans.
