The length of a road is 1 kilometre. If trees are to be planted on both sides of the road at a distance of 20 metres, how many saplings will be required?
एक सड़क की लंबाई 1 किलोमीटर है। यदि सड़क के दोनों किनारों पर 20 मीटर की दूरी पर पेड़ लगाए जाने हैं, तो कितने पौधों की आवश्यकता होगी?
Detailed Solution & Logic
Correct Answer:
102
Solution
Road length = 1 km = 1000 m
Trees are planted at every 20 m.
Number of intervals on one side:
$1000 \div 20 = 50$
Including the tree at the starting point:
50 + 1 = 51
For both sides:
$51 \times 2 = 102$
Answer: 102
