Question

If the cost of one dozen articles of the same kind is 672, what will be the cost of 18 such articles ?
​

Answer 1

Answer:

Cost of one dozen articles = ₹ 672

Cost of one article = ₹ \frac { 672 }{ 12 } = ₹ 56

Cost of 18 articles = ₹ 56 x 18 = ₹ 1008

Answer 2

Step-by-step explanation:

We know that,

1 dozen = 12

Given that,

$Cost \: of \: 12 \: articles = ₹672 \\ Cost \: of \: 1 \: article = \: ₹ \frac{672}{12} \\ Cost \: of \: 18 \: articles \: =₹ \frac{672}{12} \times 18 \\ = ₹\frac{672}{2} \times 3 \\ = \:₹336 \times 3 \\ =₹1008$

Hence cost of 18 articles is ₹1008
