Question

selling an article for rupees 690 a man gains 15% at what price should he sell it to gain 20%​

Answer 1

Answer:

720

Step-by-step explanation:

Cost price = [(selling price)/(100+gain%)]*100

                = [(690)/(100+15)]*100

                =(690/115)*100

               =6*100

               =600

20% of selling price = (600/100)*20

                                 = 6*20

                                 =120

Total = 600+120

          =720

GIVEN:-

Cost of an article after 15% gain = ₹690

TO FIND:-

Actual price = CP = $( \frac{SP \times 100}{100 + Profit} )$

$( \frac{690 \times 100}{100 + 15}) = \frac{69000}{115}$

$\frac{ \not{69000}}{ \not{115}} = ₹600$

So, the actual cost of the article is ₹600.

Selling price of article to gain 20% = ?

SOLUTION:-

$SP = ( \frac{100 + Profit}{100}) \times CP$

$SP = ( \frac{100 + 20}{100}) \times 600$

$SP = \frac{120}{100} \times 600$

$SP = \frac{120}{ \not{100}} \times { \not{600}}$

$SP = 120 \times 6$

$SP = 120 \times 6 = Rs\:720$

$SP = Rs\:720$

So, to gain 20% he have to sell the article in ₹720.

SOME RELATED FORMULAS:-

1. Profit = SP - CP
2. Loss = CP - SP
3. Profit % = (Profit × 100 / 100)%
4. Loss % = (Loss × 100 / 100)%
