Explanation

Annual salary = Rs. 6000 × 12 = Rs. 72,000

Taxable income after rebate = Rs. 72,000 - Rs. 50,000 = Rs. 22,000

Income tax = 5% of Rs. 22,000 = Rs. 1100

Explanation

5.2% of 500 = (5.2 / 100) × 500 = 26

It’s a direct percentage calculation.

Explanation

Cost Price (CP) = Rs. 950

Selling Price (SP) = Rs. 1100

Profit = SP - CP = 1100 - 950 = 150

Profit % = (Profit / CP) × 100

= (150 / 950) × 100

= 15.789%

≈ 15.8%

Explanation

The term "percent" comes from the Latin per centum, meaning "by the hundred."

So, 1% literally means 1 out of 100.

Explanation

1. Increase by 20%:

   $$100+20\%\text{ of }100=100+20=120$$

2. Apply a 25% discount on the increased price:

   $$25$$

So, the final price is 90, and the original was 100.

3. Net percentage change:

   $$frac{90 - 100}{100} times 100 = -10$$
