# 16 articles cost Rs. 72. What will be the cost of 30 articles? How many articles can be bought for Rs 207?

Answer :

Let cost price of one article be Rs. c.

Given: 16 articles cost Rs. 72.

⇒ 16 × c = 72

So, the cost price of one article is Rs. 4.50.

Now, Cost Price of 30 articles = 30c

⇒ Cost Price of 30 articles = 30 × 4.50

∴ Cost Price of 30 articles = Rs. 135

Let us assume y articles can be bought for Rs. 207.

⇒ y × c = 207

⇒ y × 4.50 = 207

Thus, the cost of 30 articles is Rs. 135 and 46 articles can be bought for Rs. 207.
