Question

if x% of y is equal to 1% of z,

Answer 1

If x% of y is equal to 1 % of z, y % of z is equal to 1 % of x and z% of x is equal to 1% of y, then the value of xy + yz + zx is equal to?

x% of y is equal to 1% of z

x/100xy = 1/100 x z

-

xy/100 = z/100

xy = Z -----(1)

y % of z is equal to 1% of x

y/100 x z = 1/100 x x

yz/100 = x/100

yz = X --

-(2)

z% of x is equal to 1% of y

z/100 x x = 1/100 x y

xz/100 = y/100

XZ = y

-(3)

We need to find the value of xy+yz+xz

→ y + x + z

→X+ y + z
