Question

Using the given information, find the total price for 6 kg of all the three items?$$\begin{array}{cccccc}Quantity\left(Inkg\right)/Price\left(₹\right)& 1& 2& 3& 4& 5\\ Gummybear& 20& 40& 60& 80& 100\\ Candies& 30& 60& 90& 120& 150\\ Chocolates& 50& 100& 150& 200& 250\end{array}$$

• A. ₹ 550
• B. ₹600
• C. ₹500
• D. ₹650

Answer 1

The correct option is B ₹600

According to the given information, direct ratio followed is different for all the items.

For gummy bear, the quantity is directly proportional to the price.
$\frac{1}{20}=\frac{2}{40}=\frac{3}{60}=\frac{4}{80}=\frac{5}{100}$

The constant is $\frac{1}{20}$
So, the price for 6 kgs can be found using the relation,
$\frac{1}{20}=\frac{6}{x}$
$\Rightarrow x=6\times 20=₹120$
So, the price for 6 kgs gummy bear is ₹120.

Similarly, the constant for
candies is $\frac{1}{30}$
So, the price for 6 kgs candies is 6 x 30 = ₹180.

and the constant for chocolates is $\frac{1}{50}$.
So, the price for 6 kgs chocolates is 6 x 50 = ₹300.

The total price for 6 kg of all the three items = 120 + 180 +300 = ₹600
