The correct Answer is:
To solve the problem, we will compute the values for both Quantity I and Quantity II step by step. ### Step 1: Calculate Quantity I **Quantity I** is defined as: \[ \text{Quantity I} = \frac{\text{Sum of single digit positive odd integers}}{\text{Sum of single digit positive even integers}} \] **Step 1.1: Identify single digit positive odd integers** The single digit positive odd integers are: 1, 3, 5, 7, 9. **Step 1.2: Calculate the sum of odd integers** \[ 1 + 3 + 5 + 7 + 9 = 25 \] **Step 1.3: Identify single digit positive even integers** The single digit positive even integers are: 2, 4, 6, 8. **Step 1.4: Calculate the sum of even integers** \[ 2 + 4 + 6 + 8 = 20 \] **Step 1.5: Calculate Quantity I** Now, we can substitute the sums into the formula: \[ \text{Quantity I} = \frac{25}{20} = \frac{5}{4} = 1.25 \] ### Step 2: Calculate Quantity II **Quantity II** is defined as: \[ \text{Quantity II} = \frac{\text{Sum of cubes of single digit positive odd integers}}{\text{Sum of cubes of single digit positive even integers}} \] **Step 2.1: Calculate the cubes of single digit positive odd integers** The cubes of the odd integers are: - \(1^3 = 1\) - \(3^3 = 27\) - \(5^3 = 125\) - \(7^3 = 343\) - \(9^3 = 729\) **Step 2.2: Calculate the sum of cubes of odd integers** \[ 1 + 27 + 125 + 343 + 729 = 1225 \] **Step 2.3: Calculate the cubes of single digit positive even integers** The cubes of the even integers are: - \(2^3 = 8\) - \(4^3 = 64\) - \(6^3 = 216\) - \(8^3 = 512\) **Step 2.4: Calculate the sum of cubes of even integers** \[ 8 + 64 + 216 + 512 = 800 \] **Step 2.5: Calculate Quantity II** Now, we can substitute the sums into the formula: \[ \text{Quantity II} = \frac{1225}{800} \] **Step 2.6: Simplify Quantity II** To simplify: \[ \frac{1225}{800} = \frac{49}{32} \approx 1.53125 \] ### Step 3: Compare Quantity I and Quantity II Now we have: - Quantity I = 1.25 - Quantity II ≈ 1.53125 Since \(1.25 < 1.53125\), we conclude: \[ \text{Quantity I} < \text{Quantity II} \] ### Final Answer Thus, the answer is: **Quantity I is less than Quantity II.** ---
