Explanation

To determine the fraction of boys in the history class when there are 12 boys and 18 girls,

we can follow these steps:

1. Calculate the total number of students in the class:

Total number of students = 12 boys + 18 girls = 30 students

2. Find the fraction of boys in the class:

Fraction of boys = Number of boys / Total number of students

= 12 boys / 30 students

= 2/5

Explanation

6, 9, 13, 16, 20, 23, ......

+3 +4 +3 +4 +3 +4

6+3 = 9

9+4 = 13

13+3 = 16

16+4 = 20

23 + 4 = 27

So, 27, 30

Explanation

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

Explanation

3+1 = 4

4+3 = 7

7+1 = 8

8+3 = 11

11+1 = 12

12+3 = 15

Explanation
