Question

If CP of 60 articles is equal to the SP of 50 articles Then gain % is__

• A. 20%
• B. 30%
• C. 10%
• D. 60%

Answer 1

The correct option is A 20%

Let the CP of each article $=x$
Then CP of $50$ articles $=50x$
Given, CP of $60$ articles $=$ SP of $50$ articles.
So, SP of $50$ articles $=60x$
Now, Gain % $=\frac{SP-CP}{CP}\times 100=\frac{60x-50x}{50x}\times 100=20$ %
