Explanation:
Let cost price be Rs x.
Given that by selling an article there is a gain of 9% and loss of 7%.
Then, 109% 0f x – 93% of x = 64
16% of x = 64
X = Rs. 400

2. A person bought an article and sold it at a loss of 10%. If he had bought it for 20% less and sold it for Rs.77 more he would have had a profit of 40%. Find the cost price of the article?

Let cost price be Rs. x
According to the question the person will get a profit of 40% if he had bought an article for 20%. Then
140% of 80% of x – 90% of x = 77
112% of x – 90% of x = 77
22% of x = 77
From this x = Rs. 350

And he should increase the S.P by 22.4-20.80 = Rs. 1.6
