Explanation

Casey can carry 4 boxes per trip.

Total boxes = 33

Number of trips = 33 ÷ 4 = 8.25

Since he can’t make a fraction of a trip, he needs 9 trips.

Explanation

To find the average:

(25 + 20 + 17 + 19) ÷ 4  

= 81 ÷ 4  

= 20.25

Explanation

Let's find the third number:

Average = (Sum of numbers) / 3

65 = (60 + 75 + x) / 3

65 × 3 = 60 + 75 + x

195 = 135 + x

x = 195 - 135

x = 60

Explanation

- 3 pointers point 3 walls in 3 minutes.

- So, 1 pointer points 1 wall in 3 minutes.

Now, we want to know how many pointers are needed to point 27 walls in 9 minutes.

Since 1 pointer points 1 wall in 3 minutes, in 9 minutes (which is 3 times longer), 1 pointer can point:

1 wall × 3 = 3 walls.

To point 27 walls in 9 minutes:

Number of pointers needed = Total walls / Walls per pointer = 27 / 3 = 9 pointers.

Explanation

We need to divide Rs. 712,000 between two towns with populations 1,800 and 1,500, in proportion to their population.

Step 1: Total Population  

1800 + 1500 = 3300

Step 2: Share per person  

712,000 ÷ 3300 = Rs. 215.76 approx.

Step 3: Each town’s share  

- Town A (1800 people):  

  1800 × 215.76 = Rs. 388,363 approx.  

- Town B (1500 people):  

  1500 × 215.76 = Rs. 323,636 approx.
