Arun makes a popular brand of icecream in a rectangular shaped bar 6cm long, 5cm wide and 4cm thick. To cut costs,the comapny had decided to reduce the volume of bar by19%. The thickness will remain the same, but the length and width will be decreased by the same percentage. the new width will be?

• volume=l*b*h=6*5*2=60cm^3
  volume is reduced by 19%
  new volume=(100-19)100*60=486000=48.6
  thickness is same but length and breadth reduces by x%
  So,new volume:(x/100*6)(x/100*5)2=48.6
  On Solving x=90
  thus length and breadth reduced by 10%
  new width=5-(10%of5)=4.5
  Ans:- 4.5

• vol of rectangle= lxbxh= 6x5x4=120cm3
  now 19% of 120 is 22.8
  so, new vol is 120-22.8= 97.2
  therefore, 97.2=(l-X)x(b-X)xh
  97.2= (6-x)(5-x)4
  x=.545
  therefore new width= 5-.545=4.45(ans)

• Thickness is 4 that make the below answer=4.92
  ans=4.92 as I think..

• length and width reduces by 10%
  so,new width=5-5(10/100)=5(1-1/10)=5*9/10=4.5

• 4.5%
  
  This is the correct answer for sure

• the new width will be less by 10 % so new width is 4.5 cm.
