Explanation

Let six consecutive even numbers be:

x, x+2, x+4, x+6, x+8, x+10

Average = (6x + 30) / 6 = x + 5 = 35

x = 30

Numbers are: 30, 32, 34, 36, 38, 40

Largest = 40

Explanation

3 dozen = 36 eggs

Price of 36 eggs = Rs. 750

Price of 1 egg = 750 ÷ 36 = Rs. 20.83

Price of 5 eggs = 20.83 × 5 = Rs. 104.17

Explanation

Let the number be x.

4x - 4 = 16 

Add 4 to both sides:

 4x = 20 

Divide by 4:

x=5

Explanation

Person B has = 55 sweets

Person A gives = 4 sweets

So, B receives 4 more sweets:

55+4=59

Explanation

Explanation

Let's denote the unknown number as 𝑥

According to the problem, the number is first multiplied by 7 and then divided by 4, resulting in 14.

This can be expressed as the equation:

7x/4 - 14

To solve for 𝑥 follow these steps:

Multiply both sides of the equation by 4 to eliminate the fraction:

7x = 14 x 4

 7x = 56 

2. Divide both sides by 7 to solve for x:

x = 56/7

x = 8 

therefore, the number is 8

Explanation

Donation = 16% of 46,000

Donation = Rs. 7,360

Remaining salary = 46,000 - 7,360

Remaining salary = Rs. 38,640

Explanation

Finding the Remaining Students

Total Boys: 20

Total Girls: 30

Total Students: 20 + 30 = 50

Students taken for the tour: 73%

Remaining percentage: 100% − 73% = 27%

Remaining students: 27% of 50

= 50 × 27 ÷ 100

= 13.5

13.5 ≈ 14 students (approximately).
