Answer 1

Step-by-step explanation:

$gain \: percent \: = \frac{sp - cp}{cp} \times 100 \\ = \frac{680 - 640}{640} \times 100 \\ = \frac{40}{640} \times 100\\ = \frac{4000}{640} \\ = 6.25 \%$

Answer 2

Answer: The gain percentage is 6.25% if C.P=₹640 and S.P=₹680.

Step-by-step explanation:

It is given in the question that
Cost price = Rs640
Selling price = Rs680
Gained amount after selling = Rs680 - Rs640 = Rs40
Rs40 is gained after selling the object at Rs680
Now, to find the gain percentage, the gained amount which is Rs40 should be divided with the original price i.e. the cost price which is Rs640 and then it is multiplied with 100.
Thus, we can write it as
⇒$\frac{Gain}{CP}$×$100$
⇒$\frac{40}{640}$×$100$
⇒$\frac{100}{16}$ = 6.25%

Hence, the gain percentage is 6.25% if C.P=₹640 and S.P=₹680.
