Question

The cost of 12 identical articles is ₹1,080. How many articles can one buy for ₹1,620?

• A. $18$
• B. $15$
• C. $6$
• D. $20$

Answer 1

The correct option is A $18$

Given, ₹1080 is the cost of 12 identical articles.

Let, one can buy $x$ articles for ₹1620, then

$\Rightarrow \frac{12}{1080}=\frac{x}{1620}$

$\Rightarrow x=\frac{12\times 1620}{1080}=18$

So, for ₹1620, one can buy 18 identical articles.
