Question

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

Answer 1

Answer:

Let the number of eggs purchased be 'x'

CP of 3 eggs=16

CP of x eggs=16/3x

SP of 5 eggs=36

SP of x eggs=36/5x

Now,

Profit=SP-CP

168=36/5x-16x/3

168=108x−80x/15

28x=168×15

28x=2520

x=90

Hence the man purchased 90 eggs.
