Profit and Loss

A man purchased some eggs at 3 for Rs. 5 and sold them at 5 for Rs. 12 thus he gained Rs. 143 in all. How many eggs did he purchase?

  1. Let the number of eggs purchased be x.
    Given: C.P of 3 eggs= Rs 5
    ⇒C.P of x eggs= Rs5/3x
    and S.P of 5 eggs= Rs 12.
    so, S.P of x eggs = Rs 12/5x
    Now profit = S.P - C.P
    ⇒143 = 12x/5-5/3x
    ⇒143 = 36x-25x/15 = 11/15x
    ⇒143×15/11 = 195
    Hence the man purchased 195 eggs.
