Question: If a man was to sell his table for Tk. 750, he would lose 25%. To gain 25% he should sell it for:

Solution:
Let the Cost price of the table be x.

Selling price = x - 25% of x
⇒ 750 = x - (25x/100)
⇒ 750 = 75x/100
⇒ 75x = 75000
∴ x = 1000

To gain 25% = 1000 + 25% of 1000
= 1000 + 250
= Tk. 1250
