Answer:
2) 1,000 trees 3) 0.425 4) 38,000 rupees
Step-by-step explanation:
2) Covert both the distance in cms.
Length if road = 4km. 800m.
= 4800m.
= 480000cms.
Distance between the trees = 9.6 m.
= 960ms.
Divide the length of the road by distance between the trees
480000/960 = 500
500 trees can be planted on each side.
1000 tress can be planted in all together.
3) Distance covered in 9 rounds = 3.825 km.
Distance covered in 1 round = 3.825/9
= 0.425km.
Pradnaya covers 0.425 km or 425 m. in 1 round.
4) Amount paid for 0.25 quintal = 9500
Therefore, Cost per quintal = Amount paid for 0.25 quintal ÷ 0.25
9500÷0.25
= 950000÷25
= 38,000 rupees
Amount per quintal is equal to 38,000 rupees.
