At a 20% loss, the selling price is = 100-20 = 80 tk
For gain of 5%, the selling price will be = 100+5 = 105 tk
Difference of two selling price = 105-80 = 25 tk
now, if the selling price increased by 25 tk, the cost price will be 100 tk
if the selling price increased by 1 tk, the cost price will be 100/25 tk
if the selling price increased by 100 tk, the cost price will be (100*100)/25 = 400 tk (Ans)
