Correct Answer: 142 m


Solution : Firstly, we will draw the diagram as per the given instructions –


Now, we have to find the shortest distance between the police station and the restaurant via the fruit shop


The approximate shortest distance between the police station and the restaurant via the fruit shop is OB + DB.
Here, OB = DB
Therefore, Distance = 2(OB)
Using the Pythagoras, we get –
(OB) 2 = (AB) 2 + (OA) 2
(OB) 2 = (60) 2 + (38) 2
(OB) 2 = 3600 + 1444
(OB) 2 = 5044
OB = 71.02
Now, on putting the value of OB, we get –
Distance = 2(OB) = 2 × 71.02 = 142.04 (approximately 142)

The approximate shortest distance between the police station and the restaurant via the fruit shop is 142m. Hence, the fourth option is correct.
