frame simple questions of SP about profit and loss​

Answer 1

Questions:

1. An article costs Rs. 450 and incurs a loss of Rs.20 . Find the Selling Price of the Article.

2. A book costs Rs. 500 and incurs a gain of 5% . Find the Selling Price of the book.

3.The cost price of 10 pens is the same as the selling price of n pens. If there is a loss of 40%, approximately what is the value of n?

Step-by-step explanation:

1.SP = CP - Loss = Rs.450 - Rs.20 = Rs.430.

2.CP = Rs.500 gain% = 5%

therefore SP = 500 + 5/100*500 = Rs.525.

3.Let the price of each pen be Re. 1.

Then the cost price of n pens is Rs. n and

the selling price of n pens is Rs. 10.

Loss = n-10.

Loss of 40% → (loss/CP)*100 = 40

Therefore, [(n-10)/n]*100 = 40 → n = 17 (approx)
