For any positive x, y and z if x is n% of y and z is m% of y then what percentage E must x be of z?
For any positive x, y and z if x is n% of y and z is m% of y then what percentage E must x be of z?
Answer/Solution
(100 × n/m)%
Steps/Work
x is n% of y MEANS x= (n/100 )* y------------------------eq1
z is m% of y MEANS z= (m/100 )* y------------------------eq2
Find equation of xz
substitute value of y from 2nd equation into Ist equation
so x= (n/100)*(100z/m)
so x= (n/m)z
or x= (100n/m)z/100
so answer E is 100n/m %.E
