• 8. The cost price of 20 articles is the same as the selling price of x articles. If the profit is 25%, find out the value of x

  1. 13
  2. 14
  3. 15
  4. 16

  Answer And Explanation

  Answer: Option D

  Explanation:

  Let the Cost Price of one article = Rs. 1
  CP of x articles = Rs. x
  CP of 20 articles = 20
  Selling price of x articles = 20
  
  Profit = 25% [Given]
  
  \begin{aligned}
  \Rightarrow \left (\dfrac{SP - CP }{CP}\right ) = \dfrac{25}{100} = \dfrac{1}{4}
  
  & \Rightarrow \dfrac{\left(20-x \right )}{x} = \dfrac{1}{4} \\
  & \Rightarrow 80 - 4x = x \\
  & \Rightarrow 5x = 80 \nonumber \\
  & \Rightarrow x = \dfrac{80}{5} = 16 \\
  
  \end{aligned}

• 10. 100 oranges are bought at the rate of Rs. 350 and sold at the rate of 48 per dozen. The percentage of profit is

  1. \begin{aligned} 12\frac{2}{7} \% \end{aligned}
  2. \begin{aligned} 13\frac{2}{7} \% \end{aligned}
  3. \begin{aligned} 14\frac{2}{7} \%\end{aligned}
  4. \begin{aligned} 15\frac{2}{7} \% \end{aligned}

  Answer And Explanation

  Answer: Option C

  Explanation:

  So before solving this question we will get the C.P. and S.P. of 1 article to get the gain percent.
  
  C.P. of 1 orange = 350/100 = Rs 3.50
  S.P. of one orange = 48/12 = Rs 4 [note: divided by 12 as 1 dozen contains 12 items]
  Gain = 4 - 3.50 = Rs 0.50
  \begin{aligned}
  Gain\% = \frac{0.50}{3.50}*100 \\
  = \frac{100}{7}\%
  = 14\frac{2}{7}\%
  \end{aligned}

• 11. A man buys an item at Rs. 1200 and sells it at the loss of 20 percent. Then what is the selling price of that item

  1. Rs. 660
  2. Rs. 760
  3. Rs. 860
  4. Rs. 960

  Answer And Explanation

  Answer: Option D

  Explanation:

  Here always remember, when ever x% loss,
  it means S.P. = (100 - x)% of C.P
  when ever x% profit,
  it means S.P. = (100 + x)% of C.P
  
  So here will be (100 - x)% of C.P.
  = 80% of 1200
  = 80/100 * 1200
  = 960
