Question 1

33 Officers and 75 Ratings are each allocated 4 white t-shirts and 2 blue t-shirts. How many t-shirts are issued in total?

Accepted Answer

648

Answer

Explanation:
To find the total number of t-shirts, multiply the number of officers and ratings by the total number of t-shirts each receives, then add them together. For officers: 33 officers × (4 white t-shirts + 2 blue t-shirts) = 33 × 6 = 198 t-shirts. For ratings: 75 ratings × (4 white t-shirts + 2 blue t-shirts) = 75 × 6 = 450 t-shirts. Adding these together gives a total of 198 (officers) + 450 (ratings) = 648 t-shirts. Therefore, the total number of t-shirts issued is 648.

Question 2

What ONE number can replace BOTH question marks?

1/? = ?/36

Accepted Answer

6

Answer

Explanation:
To find the missing number, cross multiply: 1 × 36 = 6 × ?. This simplifies to 36 = 6?. Divide both sides by 6:36/6 = 6?/6. This gives 6 = ?. Therefore, the missing number that can replace both question marks is 6.

Question 3

3b + 7c = 7c +  therefore  equals?

Accepted Answer

3b

Answer

Explanation:
In the given equation 3b + 7c = 7c+, we can see that the term 7c is present on both sides. By subtracting 7c from both sides of the equation, it cancels out, leaving 3b = on one side. Therefore, the equation simplifies to 3b =, indicating that 3b is the result.

Question 4

20% of 60 equals?

Accepted Answer

12

Answer

Explanation:
To find 20% of a number, you multiply the number by 0.20 or simply move the decimal point two places to the left. Therefore, 20% × 60 = 0.20 × 60 = 12. So, 20% of 60 is 12.

Question 5

If you multiply a whole number by 4 and then divide it by 2, what will the final answer be?

Accepted Answer

Always twice the original number

Answer

Explanation:
When you multiply a whole number by 4, you increase its value by a factor of 4. Then, when you divide it by 2, you halve the result. Halving a number is equivalent to multiplying it by 0.5, which is half. So, in total, you are effectively multiplying the original number by 2. Therefore, the final answer will always be twice the original number.
