Answer 1

The formula used to calculate the profit in a transaction is, Profit = Selling price - Cost price, and the formula used to calculate loss is, Loss = Cost price - Selling price.

The formula to calculate the profit percentage is: Profit % = Profit/Cost Price × 100. The formula to calculate the loss percentage is: Loss % = Loss/Cost Price × 100.

Use these formulas to solve the questions.

Answer 2

Answer:

$\huge\fbox \red{A}\fbox \green{N}\fbox \purple{S}\fbox \orange{W}\fbox \red{E}\fbox \blue{R}$

Let CP = x

SP = x + 20% of x = 1.2 x

New CP = x - 100

New SP = 1.2x - 100

New profit,

1.2x - 100 - x + 100 = 0.2x

New profit = 25 % of (x - 100)

25 % of (x - 100) = 0.2x

0.2x = [25 *(x - 100) / 100]

20x = 25x - 2500

5x = 2500

x = 500

• So, the cost price was Rs. 500
