Question

Decla sold her gold necklace at a profit of 7%. If she had sold it for 294 more, she would have got
10% profit. Find the cost price.​

Answer 1

Answer:

9800

Step-by-step explanation:

Difference of profit in % = 10% - 7% = 3%

Difference of Profit in value = 294

Thus, cost price = 294/3% = 294/0.03 = 9800

Answer 2

Answer:

Let the cost price of the necklace be 'x' Rs.

The selling price at 7 % = x + (x*7/100)

= x + 7x/100

= 107x/100

And,

Selling price at 10 % profit = x + (x*10/100)

= x + 10x/100

= 110x/100

Now, according to the question.

110x/100 - 107x/100 = 294

3x/100 = 294

3x = 294*100

x = 29400/3

x = 9800

So, the cost price of the necklace is Rs. 9800.
