Some fruits are bought at 11 for Rs. 100 and twice the number at 8 for Rs. 100. If all the fruits are sold at 9 for Rs. 100, then what is the profit or loss percentage?

2\(\frac{2}{9}\)% loss

            Price   :    Qty

Buy₁:    100    :     11         ) × 8  × 1

Buy₂:    100    :     08         ) × 11 × 2             (To make twice qty)

⇒

Buy₁:    800     :     88

Buy₂:    2200   :     176   

Buy :    3000    :     264

            1000    :      88

Sell :     100     :      09

           1000     :      90

He purchased 88 articles in Rs. 1000 and sold 90 articles in Rs.1000. Therefore, there is a loss of 2 articles on selling 90 articles.

Hence,

Loss% = \(\frac{2}{90}\) × 100% = 2\(\frac{2}{9}\)%
