Solution:Here Selling price is same.
No profit and no loss condition
Profit earned on 1st item will be equal to
loss occured on 2nd item.
Fractional value of 20% = 1/5
For 1st item ⇒ 6 units = 2400 Rs
Profit (1 unit) = 400 Rs.
Therefore, Loss occurred on the second
item will also be equal to 400 Rs.
