Question

When a person sold an article, his profit percent is 175% of the cost price. If the cost price is increased by
45% and the selling price remains the same, then find his new profit is what percent of the selling price of the​

Answer 1

Explanation:

Let the cp of the article is x rs and his profit is =(175x/100)=7x/4 rs

So, the sp is = (x+7x/4)=11x/4 rs=55x/20 rs

Now, the new cp becomes =(145x/100)=29x/20 rs

So, the new gain is =(55x/20–29x/20)=26x/20 rs

So, his new gain % is =(26x/20*20/29x*100)=2600/29%=89.655%(approximately) (ans)

And, the new profit is y% of the sp (let)

So, 55x/20*y/100= 26x/20

Or, y =520/11=47.2727% (ans)

Hope it's help you
