Question

If the cost price of $6$ articles is equal to the selling price of $4$ articles, then the gain percent is

• A. $35\%$
• B. $45\%$
• C. $40\%$
• D. $50\%$

Answer 1

The correct option is D $50\%$

Let the cost price of $1$ article be $\text{Rs}100$

cost of $4$ article will be $\text{Rs}400$

Cost of $6$ articles will be $\text{Rs}600$

As said in the question cost of $6$ articles is same as the selling of $4$ articles

so,selling price of $4$ article is$=\text{Rs}600$

cost price is $\text{Rs}400$

Profit$=(600-400)=\text{Rs}200$

Gain percentage$=\frac{200}{400}\times 100=50\%$

$50\%$ is the gain percant
