A reduction of 20% in the price of eggs will enable one to buy 4 dozen more eggs for Rs. 80. What is the original price per dozen?

Choose one answer.
a. Rs. 5
b. Rs. 6
c. Rs. 6.5
d. Rs. 7

• let the price of eggs per dozen=x
  total no of dozens for 80=80/x
  20% reduction
  so,rate for dozen=(80/100)*x
  now total no of dozens he can buy =80/{(80/100)*x}
  according to question
  80/{(80/100)*x}=(80/x)+4
  100/x=80/x +4
  20/x=4
  x=5
  so option a is correct

• let the price of dozen eggs be x
  no of dozens=80/x
  now price is 0.8x
  now total no of dozens=80/0.8x
  so at last 80/0.8x=80/x+4
  so 80*0.2/0.8x=4
  by solving x=5

• let the price of dozen eggs be x
  no of dozens=80/x
  now price is 0.8x
  now total no of dozens=80/0.8x
  so at last 80/0.8x=80/x+4
  so 80*0.2/0.8x=4
  by solving x=5
