Once you attempt the question then PrepInsta explanation will be displayed.
Reference:
In a city, Fruit lane was to the north-west of Jewellery lane.
Grocery lane was in the east of fruit lane which was towards the south of vegetable lane.
Toy lane was towards the south-west of grocery lane such that it was situated towards the east of Jewellery lane.
Inference:
From the above hints following image can be made.

Reference:
Clothes lane was 20 km towards the north of Jewellery lane, which was 4 times the distance between Jewellery lane and Toy lane.
Inner circle was the mid point between Fruit lane and Grocery lane and also Jewellery lane and Clothes lane.
The distance between Vegetable lane and fruit lane was half of the distance between Clothes lane and Inner circle.
Inference:
As the distance between clothes lane and Jewellery lane is 20 km, thus as per the first hint distance between Jewellery lane and Toy lane must be 5km.
As Inner circle is the mid point between clothes lane and Jewellery lane, thus its distance with clothes lane must be 10 km, thus the distance between fruit lane and vegetable lane must be 5km

If the distance between the Fruit Lane and the Grocery Lane is 14 km, the distance from the Fruit lane and the Inner Circle will be = 7 km
Therefore, total distance covered = 7 + 10 + 5 = 22 km
