Explanation

If 8 workers can do a job in 6 hours, it means that the total work required to complete the job is 8 x 6 = 48 man-hours.

If 12 workers are assigned to do the same job, the total work required remains the same, but the number of workers has increased. To find the time it will take 12 workers to do the same job, we can divide the total work by the number of workers:

48 man-hours ÷ 12 workers = 4 hours

Therefore, the correct answer is: Four hours.

Explanation

Fabric Let's first find out how many shirts can be made from 1 meter of fabric:

6 meters of fabric = 2 shirts

1 meter of fabric = 2/6 shirts = 1/3 shirt

Now, let's find out how many shirts can be made from 42 meters of fabric:

42 meters of fabric = 42 × 1/3 shirts = 14 shirts

Therefore, the correct answer is: 14.

Explanation

To find the annual rent, multiply the monthly rent by 12:

5000 rupees/month × 12 months/year = 5000 × 12 = 60,000 rupees/year

Therefore, the correct answer is: 60,000.

Explanation

To find the outer edge of the park, we need to calculate its perimeter. The formula for the perimeter of a rectangle is: Perimeter = 2(Length + Width)

Perimeter = 2(84 + 56)

= 2 x 140

= 280

Therefore, the outer edge of the park is 280 meters.

Explanation

To find the capacity of the largest drum, we need to find the Highest Common Factor (HCF) of 15, 20, and 25.

Factors of 15: 1, 3, 5, 15

Factors of 20: 1, 2, 4, 5, 10, 20

Factors of 25: 1, 5, 25

The HCF among these numbers is 5.

The correct answer is: 5.

Explanation

Let's find the smallest number of apples that can be divided among 15, 10, and 20 children:

Multiples of 15: 15, 30, 45, 60, ...

Multiples of 10: 10, 20, 30, 40, 50, 60, ...

Multiples of 20: 20, 40, 60, ...

Find the smallest number that appears in all three lists: 60

The correct answer is: 60

Explanation

To find the largest number (HCF) that divides 12, 6, 3, and 24.

Factors of 12: 1, 2, 3, 4, 6, 12

Factors of 6: 1, 2, 3, 6

Factors of 3: 1, 3

Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24

Therefore, the largest number (HCF) that divides 12, 6, 3, and 24 is 3.

The correct answer is: 3

Explanation

To find the smallest number that can be divided by 15, 10, and 5, we need to find the Least Common Multiple (LCM) of these numbers.

The multiples of 15 are: 15, 30, 45, 60, ...

The multiples of 10 are: 10, 20, 30, 40, ...

The multiples of 5 are: 5, 10, 15, 20, 25, 30, ...

The smallest number that appears in all three lists is 30, which means that 30 is the Least Common Multiple (LCM) of 15, 10, and 5.

Therefore, the smallest number that can be divided by 15, 10, and 5 is indeed 30.

The correct answer is: 30
