Question

What is the total number of coffee consumers found across all the five cities together ?

• A. 3210
• B. 3310
• C. 3110
• D. 3515

Hint:

To perform fast summation, add the hundreds digits first:
\[ 6 + 6 + 5 + 6 + 7 = 30 \quad (\rightarrow 3000) \] Then add the tens digits:
\[ 0 + 70 + 90 + 50 + 0 = 210 \] Total $= 3000 + 210 = 3210$. This visual regrouping saves time.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
To find the total number of coffee consumers across all five cities, we need to extract the individual coffee consumption values for each city (P, Q, R, S, and T) from the dataset and calculate their sum.

Step 2: Detailed Explanation:
Let us identify the number of coffee consumers in each city from the provided table:
- City P: 600
- City Q: 670
- City R: 590
- City S: 650
- City T: 700
Now, sum these individual values step-by-step:
\[ \text{Total Coffee Consumers} = \text{Coffee}_P + \text{Coffee}_Q + \text{Coffee}_R + \text{Coffee}_S + \text{Coffee}_T \] \[ \text{Total Coffee Consumers} = 600 + 670 + 590 + 650 + 700 \] Let us break down the addition to avoid errors:
- Combine P and Q: \( 600 + 670 = 1270 \)
- Add R to the result: \( 1270 + 590 = 1860 \)
- Add S to the result: \( 1860 + 650 = 2510 \)
- Add T to the result: \( 2510 + 700 = 3210 \)
The total number of coffee consumers across all five cities is 3210.

Step 3: Final Answer:
The correct option is (A).
