Question

A man sold 10 eggs for 5 Rs. and gained 20%. how many eggs did he buy for 5 Rs?

Answer 1

Let
we have the price of each egg before gain = x rs
Total Gained by the man = 20%
Total gained in terms of price = x + 20 x100 =
6x5
Cost of 10 eggs =5 rs
Then it can be represented as:
Let number of eggs buy in 5 rs = y
Cost gain no. of eggs
5 6x5 10
5 x y
⇒y10 = 6x5×55 x
⇒y10 = 65
y = 12
So,
He buy 12 eggs in 5 rupee . ( Ans )
