प्रश्न
A road is 4 km 800 m long. If trees are planted on both its sides at intervals of 9.6 m, how many trees were planted?
उत्तर
Total length of the road = 4 km 800 m
= 4 km + 800 m
= 4000 m + 800 m ...........(1 km = 1000 m)
= 4800 m
Distance between two plants = 9.6 m
∴ Number of trees planted on each side of the road = (Total length of the road ÷ Distance between two plants) + 1
= 4800 m ÷ 9.6 m) + 1
= `(4800/1 ÷ 96/10) + 1`
= `(4800/1 xx 10/96)+ 1`
= `(48000/96) + 1`
= 500 + 1
= 501
∴ Total number of trees planted on both sides of the road = Number of trees planted on each side of the road × 2
= 501 × 2
= 1002
Thus, the number of trees planted on both sides of the road is 1002.
