Question

x% of y is z then what %of z is x​

Answer 1

Step-by-step explanation:

the answer is (1000/y)%

solution:

x*y/100 = z as per mentioned in the question:

100z=xy

z*100/y = x

(lets multiply numerator and denominator by 100)

z*(100*100)/(y*100)=x

so finally z*(10000/y)/100=x

lets check this with an example:

x=800

y=25

so , 25% of 800 is 200

z=200

so (10000/y)% of z should be equal to x,

200 (*10000/(25*100)) should be equal to 800

200 * 10000/2500

or 200*4=800

check it with another example

x=80

y=20

so 20% of 80 is 16.

Now 10000/y % of 16 should be equal to 80.

lets solve it

16*(10000/20*100) should be equal to 80

16* (10000/2000)

16*5 =80 .

which proves : 10000/y % of z is equal to x

this is ur answer.....☺️☺️☺️

u need any further help ask me.....okk,!!!!☺️☺️☺️

Answer 2

Answer:

x is (10,000/ y )% of z.

Step-by-step explanation:

✅x% of y = z

✅( x/100 ) × y = z

On rearranging :

✔️x × ( y/100 ) = z

✔️x = z × 100/ y

✔️Or x = [ (100z / y )/ z ] x 100 %

✔️x = ( z/y/z ) × 10,000 %

✔️x = ( 10,000/ y ) %
