Michael lives 10 km away from where I live. Ahmed lives 5 km away and Susan lives 7 km away from where I live. Arun is farther away than Ahmed but closer than Susan from where I live. From the information provided here, what is one possible distance (in km) at which I live from Arun’s place?
6.02
To determine a possible distance at which Arun lives from the narrator's place, we need to interpret the given information about the distances of Michael, Ahmed, and Susan, and then apply the conditions provided for Arun's location.
First, let's list the known distances from where the narrator lives to each person's place:
The problem states two specific conditions regarding Arun's distance:
Let's use \(D_{Arun}\) to represent the distance of Arun from the narrator's place.
Ahmed lives 5 km away. If Arun is farther away than Ahmed, it means Arun's distance must be strictly greater than Ahmed's distance.
Mathematically, this can be written as:
\(D_{Arun} > \text{Ahmed's distance}\)
\(D_{Arun} > 5 \text{ km}\)
Susan lives 7 km away. If Arun is closer than Susan, it means Arun's distance must be strictly less than Susan's distance.
Mathematically, this can be written as:
\(D_{Arun} < \text{Susan's distance}\)
\(D_{Arun} < 7 \text{ km}\)
By combining both conditions, we can establish a precise range for Arun's distance. Arun's distance must be greater than 5 km AND less than 7 km.
So, the possible range for Arun's distance is:
\(5 \text{ km} < D_{Arun} < 7 \text{ km}\)
This means Arun lives at any distance between 5 km and 7 km, but not exactly 5 km or 7 km.
Now, let's examine the provided options to identify which one falls within the calculated range of \(5 \text{ km} < D_{Arun} < 7 \text{ km}\).
| Option | Distance (km) | Satisfies \(5 < D_{Arun} < 7\)? | Explanation |
|---|---|---|---|
| 1 | 3.00 | No | 3.00 is not greater than 5. |
| 2 | 4.99 | No | 4.99 is not greater than 5. |
| 3 | 6.02 | Yes | 6.02 is greater than 5 (6.02 > 5) AND 6.02 is less than 7 (6.02 < 7). This distance fits the criteria. |
| 4 | 7.01 | No | 7.01 is not less than 7. |
Based on our analysis, only 6.02 km falls within the specified range for Arun's distance. Therefore, 6.02 km is a possible distance at which the narrator lives from Arun's place.
