Question

The cost of 50 articles is ₹ 2850. Find the cost of 120 such articles

• A. ₹ 6480
• B. ₹ 6840
• C. ₹ 7852
• D. ₹ 1250

Answer 1

The correct option is B

₹ 6840

Ratio of the cost of the article = Ratio of the number of items

Let the cost of 120 such articles be $x$

Then 50 : 120 = ₹ 2850 : $x$

$\Rightarrow \frac{50}{120}$ = $\frac{2850}{x}$

$\Rightarrow 50\times x=120\times 2850$

$\Rightarrow x=\frac{120\times 2850}{50}$

$x$ = ₹ 6840
