Question

By selling an article for rs 3300 a person gains 1/12 of his cost price.If the sells it for rs 3360 , then what is his gain percentage in decimal.

Answer 1

Answer:

10.3 %

Step-by-step explanation:

Let Rs. x be the cost price

Now, from the above information, we can form the equation:

3300 = x+(x/12) as he has gained 1/12 of his cost price x.

equation can be simplified to:

3300 = ((12x+x)/12)

or, 3300 = 13x/12

or, 13x = 39600

or, x = 3046.15 Rs

Now if he sells it for Rs. 3360, his profit is:

3360-3046.15=313.85

Therefore, his gain percentage is:

(313.85/3046)×100

=10.3 %
