1. If 90% of A =30% of B and B=x% of A, then the value of x is?
(1) 800
(2) 300
(3) 700
(4) 400
(5) None of these

• 0.9 A= 0.3 B
  so b=3A means 300% of A

• 90% of A = 30%of B, (90/100)A= (30/100)B
  
  A= (30/90)*B ==> A=(1/3)*B
  B=(x/100)*A ==> B=(x/100)*(1/3)B
  B = (XB/300) ==> X= 300

• 90*A/100=30*B/100
  B=A*3
  X=300

• none of these
  90/100XA=30/100XB--(1)
  B=X/100XA--(2)
  solving 1 & 2 equations
  we get x=3/100
