Answer 2

Let the number of articles to be purchased be 'x'.

(i) Given that he buys 5 oranges at the rate of 5 per rupee.

So, the cost price = (x/5)

(ii) Given that he buys same number of oranges at the rate of 4 per rupee.

So, the cost price = x/4.

Hence, the cost price of these 2 oranges = (x/5) + (x/4) = (5x + 4x)/20 = 9x/20.

Now,

Given that he sells all of them at the rate of 9 for rupees 2.

So, total selling price = (2x/9) * 2

                                   = 4x/9.

Here, Cost Price > Selling price. So, Loss has occured.

We know that Loss = Cost price - Selling price

⇒ (9x/20) - (4x/9)

⇒ (81x - 80x)/180

⇒ x/180.

But, Given that he incurs a loss of 30 rupees.

⇒ x/180 = 30

⇒ x = 5400

Hence, the number of articles he bought:

⇒ 2x

⇒ 2(5400)

⇒ 10800.

Therefore, the number of articles that he purchased = 10800.

Hope this helps!
