Soni can cycle from point A to point B and return to point A in 10 min...
Let time for cycling = x and time for walking = y
We have,
x+x = 10,
2x = 10
x+y = 18
x = 5
∴ y = 13
Hence time in walking from both sides = 26 minutes.

Soni can cycle from point A to point B and return to point A in 10 min...
Analysis:
Let's assume that the distance between point A and point B is x.
First scenario:
In the first scenario, Soni cycles from point A to point B and returns to point A in 10 minutes. This means that she spends 10 minutes cycling and 0 minutes walking.
Second scenario:
In the second scenario, Soni cycles from point A to point B and then walks back from point B to point A in 18 minutes. This means that she spends some time cycling and some time walking.
Calculating the time spent cycling:
If Soni cycles from point A to point B and then walks back, it takes her 18 minutes in total. Since it takes her 10 minutes to cycle both ways, she spends 18 - 10 = 8 minutes walking.
Calculating the time spent walking:
In the first scenario, Soni spends 0 minutes walking. In the second scenario, Soni spends 8 minutes walking.
Calculating the total time spent walking there and back:
Since Soni spends 8 minutes walking in the second scenario, it would take her 8 + 8 = 16 minutes to walk there and back.
Answer:
The correct answer is option B) 16 minutes.
