Question

manju purchased refrigerator for 15000/- what should be selling price to earn profit of 25%​

Answer 1

Answer:

As we know that every value is a 100% value in it's own so cost price is also a 100% value

Selling price = Cost price + % profit

Selling price = Cost price - % loss

And also we know that selling price increases or decreases by the same percentage as we face % profit or loss

By selling a plot for Rs.18700 the owner faced a loss of 15% it means that given Rs.18700 is a 85% value of cost price because whenever a value reduces by 15% it remains 85%

Cost price or 100% of this will be (18700*100)/85 or 22000

To gain 15% profit he must sell the plot at 115% of cost price

Selling price of plot at 15% profit = (22000*115)/100 or 25300 Rs.

Or

In one step :-

Selling price of plot at a profit of 15%

(18700*115)/85 = 25300

The given value 18700 is being multiplied by 115% because the person wants to earn a profit of 15% and to gain a profit of 15% he must sell the plot at 115%

But the given value 18700 is being divided by 85% because it's a 85% value of original value or cost price
