Q. A city plans to reduce its carbon emissions by 20% over the next 5 years. If the current emissions are 5000 tons, what will be the target emissions after 5 years?
Q. A conservation project aims to plant trees in a deforested area. If they plant 150 trees in the first year and plan to increase the number of trees planted by 10% each subsequent year, how many trees will they plant in the third year?
A.
165 trees
B.
180 trees
C.
195 trees
D.
200 trees
Solution
Year 1: 150 trees. Year 2: 150 + (0.10 * 150) = 165 trees. Year 3: 165 + (0.10 * 165) = 181.5, rounded to 195 trees.
Q. A country aims to reduce its greenhouse gas emissions by 30% over the next 5 years. If the current emissions are 1,200 million tons, what will be the target emissions?
A.
840 million tons
B.
900 million tons
C.
1,000 million tons
D.
1,200 million tons
Solution
1,200 million tons - (30/100 * 1,200) = 1,200 - 360 = 840 million tons
Q. A park is planning to reduce its energy consumption by 15% next year. If the current consumption is 8000 kWh, what will be the new consumption after the reduction?
A.
6800 kWh
B.
7000 kWh
C.
7500 kWh
D.
7200 kWh
Solution
15% of 8000 kWh = 0.15 * 8000 = 1200 kWh. New consumption = 8000 - 1200 = 6800 kWh.
Q. A solar panel installation reduces electricity costs by 40%. If the original cost was $500 per month, what will be the new cost after the reduction?
A.
$300
B.
$250
C.
$350
D.
$400
Solution
40% of $500 = 0.40 * 500 = $200. New cost = 500 - 200 = $300.
Q. If a river's pollution level is reduced by 25% and the current level is measured at 200 units, what will be the pollution level after the reduction?
A.
150 units
B.
175 units
C.
200 units
D.
180 units
Solution
25% of 200 = 0.25 * 200 = 50 units. New pollution level = 200 - 50 = 150 units.
Q. If the population of a city is 1 million and the average carbon footprint per person is 4 tons per year, what is the total carbon footprint of the city?
