Hints: Let cost price of an article x

When SP is 340 Tk, then gain % = 340 - x /x ×100

When SP is increased, if 5% more is gained by selling an article for 350 TK. than by selling if for 340 TK.

Then, [ (350 - x)/x ×100] - [ (340 - x)/x × 100 ] = 5

100/x [ 350 - x - 340 + x ] = 5

100/x [10] = 5

x = 1000/5 = 200 TK.

Let, Cost price = x

5% of cost price = $x \times \frac{5}{100}$

Now, 350 - 340 = $x \times \frac{5}{100}$

=> 10 = $x \times \frac{5}{100}$

=> 1000 = 5x

=> x = 200
