Rahul is a cashew merchant in Kerala. He has cashews in sealed wooden boxes of 10kg

each. The price of the cashew increases by Rs.20 per kg for every year, but at the same

time, 10% of the cashews are eaten by rodents every year. If the price of a 1 kg of fresh

cashew is Rs.100, what is the change in his profits if he sells a sealed box after one year of

storage, rather than selling it fresh? (In Rs.)

A) 64 more

B) 64 less

C) 80 more

D) 80 less

• c)80 more.
  
  Price of 1kg fresh cashew = Rs.100
  Therefore, price of 10kg = Rs.100 * 10 = Rs.1000
  
  10% of 10kg which eaten by rodents = 10*10/100 = 1kg.
  
  So, End of Year he had 10kg - 1kg = 9kg
  
  So, he sells that 9kg with Rs.20 per kg profit = 9 * 120 = 1080.
  
  He buy 10kg wooden box with cashew for 1000Rs and sell that for 1080Rs.
  
  So, profit = 1080 - 1000 = 80Rs more money he get.

• Answer is C 80 More
  
  If he sells without waiting, total income would be 1000
  
  upon waiting, cost will become 9*120 = 1080 (Becuiase 20 rupees per kg is going to be increase per year and 10% of the cashews are eaten by rodents every year )
  
  So Profit is 80 rupees

• the answer will be C (80 More)
  the cost of fresh cashews = 10*100=>1000 rs.
  and after 1 year the 10% cashews will be eaten so remaines are 10% of 10kg=> 9kg cashews.
  the price of 1 kg cashews will get increase by 20rs/kg i.e. it becomes 120 rs/kg
  so total selling price of 9kg cashews become =120*9=>1080rs.
  so total profit=1080-1000=80 rs. Answer. dats it.

  Explanation : S.P of one box today = 10*100 =1000 Rs
  Quantity remaining after an year = 10 - (.1*10) = 9kg
  S.P after an year = 9*120 = 1080
  Extra Profit = 1080-1000= Rs 80

• 10kg=1000rs
  after one year 10kg=1200(20rs increase in per kg)
  10% of cashew are eaten ,so 1 kg will be lost after one year.
  9% of cashew =1080rs(after one year).
  C)80 more
