Explanation

• 30% of 100 = 30
• 3% of 1000 = 3/100 × 1000 = 30
• So, 30% of 100 is equal to 3% of 1000.

Explanation

To find the mean, add the numbers and divide by the total count:

9 + 0 + 5 + 1 + 0 = 15

Total count = 5

Mean = 15 / 5 = 3

Explanation

To find how many more men are needed, we can use the formula for work:

$$text{Work} = text{Men} times text{Days}$$

Initially, 120 men can complete the work in 90 days. The total work can be represented as:

$$120 times 90 = 10800 text{ man-days}$$

Now, we need to find how many men are needed to complete the work in 40 days:

$$text{Required Men} = frac{10800}{40} = 270 text{ men}$$

Explanation

Arithmetic mean of 2, 4, 6, 8, 10, and 12
A.M = Sum of terms / No. of terms
A.M = (2 + 4 + 6 + 8 + 10 + 12) / 6
A.M = 42 / 6
A.M = 7

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
