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 present of the selling price of article
​

Answer 1

Answer:

Let the cp of the article is x rs and its sp is =(175x/100)=7x/4 rs =35x/20 rs

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

So, the new gain is =(35x/20–29x/20)=6x/20 rs

So, his new gain % is =(6x/20*20/29x*100)=600/29%=20.69%(approximately) (ans)

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

So, 35x/20*y/100=6x/20

Or, y =120/7%=17 (1/7)% (ans)
