Q. A food processing unit recieved a fresh consigment of berries from himanchal berry corporation containing 'a' kg of berries.After analysis these berries were found to contain 99% water. After 15 days sample of berries from the lot were containing 98% of water.what must be the wieght of same lot at that time?

• a/2 kg
  In 'a' kg of fresh berries, solid material is 0.01 a kg which is 0.02 x kg where x is total weight after 15 days
  so x= .01a/.02
  =a/2 kg

• Let R is total then starting a(99%100)=0.01a
  after 15 days (98%100)=0.02
  so total is R=0.01a%0.02
  R=a/2

  1= 2%
  50=100%
