If x% of a is the same as y% of b, then z% of b is :

a. (xy/z)% of a
b. (yz/x)% of a
c. (xz/y)% of a
d. None of these

• (x/100)a=(y/100)b
  b=(ax)/y
  z%b=(xz/y)%a
  ans is c

• x% of a = xa/100..................1
  y% of b = yb/100..................2
  1=2
  xa/100=yb/100
  =>xa=yb
  =>b=ax/y
  z% of b = zb/100.................3
  putting the value of b in 3
  z(ax/y)/100
  axz/y100
  so, (xz/y)% of a
  ans c

• x/100 * a = y/100 * b
  
  b=x*a/y,
  
  (xz/y)% of a
• 11 years agoHelpfull: Yes(3) No(1)
• from the condition b= (x/y)of a
  z%of b = z% of (x/y) of a =(xz/y)% of a
  ans c
• 11 years agoHelpfull: Yes(3) No(1)
• (x/100)a = (y/100)b
  From here
  b=(ax/y)
  Z%b = (z/100)b
  by substituting value of b we get,
  Z%b = (xz/y)%a
  
  So,answer is "C"

• x% of a= xa/100
  y% of b=yb/100
  xa=yb
  b=xa/y
  
  z% of b= zb/100
  =zxa/(100.y) = (zx/y)% of a
  so answer is c

• ANS is c.
  simply put the value of b in z%of b eq-1
  Given:
  x% of a=y% of b
  so,b=(x/y)%b
  put this value in eq 1 you will get c as ans.

• ans ic (xz/y)%of a
• 11 years agoHelpfull: Yes(1) No(0)
• ax/100 = by/100
  => ax = by
  => b= ax/y
  therefore, zb/100 = (xz/y)/100 * a

• x% of a = (x/100)a , y% of b = (y/100)b
  given that
  x% of a = y% of b
  => (x/100)a = (y/100)b
  b = (x/y)a
  z% of b = (xz/y)% of a
  i.e option (c)
