Explanation

To find how many times digit 3 appears from 1 to 100, count how often it appears in:

1. Units place:

Numbers with 3 in units place:  

3, 13, 23, 33, 43, 53, 63, 73, 83, 93 → 10 times

2. Tens place:

Numbers with 3 in tens place:  

30–39 → 10 times

Explanation

Given:  

Discount = 20%  

Selling Price (after discount) = Rs. 70  

We need to find the Marked Price.

---

Step-by-step solution:

Let Marked Price = x

After 20% discount, the customer pays 80% of the marked price.

So,  

80% of x = 70

Convert to equation:  

(80/100) × x = 70  

⇒ (4/5) × x = 70

Multiply both sides by 5:  

4x = 350

Now divide both sides by 4:  

x = 350 ÷ 4 = 87.5

Marked Price = Rs. 87.50

The answer is equal by putting value 10.

Explanation

Percent means 'per 100'.

So, 5.3% means 5.3 per 100 or simply 5.3/100.

If you divide 5.3 by 100, you'll get 0.053

Explanation

- Average of 5 quantities = 6  

  So, total sum of 5 = 5 × 6 = 30  

- Average of 3 quantities = 4  

  So, total sum of 3 = 3 × 4 = 12  

- Sum of remaining 2 = 30 − 12 = 18  

- Average of remaining 2 = 18 ÷ 2 = 9

Explanation

Average of 5, 6, 7, and X = 10

Use the average formula:

(5 + 6 + 7 + X) / 4 = 10

Add the numbers:

(18 + X) / 4 = 10

Multiply both sides by 4:

18 + X = 40

Now solve for X:

X = 40 - 18 = 22
