Question

A man purchased some egg at 3 for Rs 16 and sold them at 5 for RS 36. Thus, he gained RS 168th all. How many eggs did he purchaser?​

Answer 1

Answer:

Let the number of eggs purchased be 'x'

CP of 3 eggs =Rs.16

CP of x eggs = 16x/3

SP of 5 eggs =Rs.36

SP of x eggs = 36x/5

Now,

Profit = SP−CP

168 = 36x/5 - 16x/3

168 = 108x−80x/15

28x = 168×15

28x = 2520

x = 90

Hence the man purchased 90 eggs.
