Product of two numbers is cost. If one number is increased by 50% then other number is decreased how much….

• 33.33%
  
  As let X*Y=A
  then Y=A/X
  
  now X=1.5X
  so 1.5X*Z=A
  Z=A/1.5X
  Z=66.67Y
  
  So Y is decreased by 33.33%

• 33.33% is the answer
  X*Y=C AND (X+(X/2))*Z=C
  solving the equations we get Y=1.5Z ie,Z=(Y/1.5)
  so Z is 66.67% of Y ie,(Y/1.5)is 66.67% of Y
  
  So 33.33% is the decrease in Y
