Explanation

Using formula:

$b^2-4ac=0$

Here:

• $a = 2$
• $b=-k$
• $c = 5$

So:

(−k)^2−4(2)(5)=0
k^2−40=0
k^2=40

±2√(10)

Explanation

Assume cost price = 100

Marked price = 25% above CP:

$$100+25=125$$

Discount = 10% on 125:

$$10\%\text{ of }125=12.5$$

Selling price:

$$125-12.5=112.5$$

Profit

$$112.5 - 100 = 12.5$$

Explanation

Explanation

Let original price = x

Step 1: Apply 25% discount

Discounted price =

$$x-25\%\text{ of }x=0.75x$$

Step 2: Apply tax (55% on discounted price)

Final price =

$$0.75x\times 1.55=1.1625x$$

Given final price = 1260

1.1625x=1260
x=1260​/1.1625=1083.87≈1084
