Q. A country plans to increase its national park area by 15% each year. If the current area is 200 square kilometers, what will be the area after 1 year? (2023)
A.
230
B.
240
C.
250
D.
260
Solution
Area after 1 year = 200 * 1.15 = 230 square kilometers.
Q. A country plans to reduce its carbon emissions by 10% each year. If the current emissions are 500 tons, what will be the emissions after 1 year? (2022)
A.
450 tons
B.
400 tons
C.
500 tons
D.
550 tons
Solution
Emissions after 1 year = 500 - (10% of 500) = 500 - 50 = 450 tons.
Q. A country signed a treaty that will reduce its carbon emissions by 30%. If its current emissions are 2 million tons, what will be the new emissions after the reduction?
A.
1.4 million tons
B.
1.5 million tons
C.
1.6 million tons
D.
1.7 million tons
Solution
New emissions = Current emissions - (30% of Current emissions) = 2 million tons - (0.3 * 2 million tons) = 1.4 million tons.
Q. A data set has a mean of 20 and a variance of 16. What is the range of the data if it is normally distributed? (2023)
A.
8
B.
16
C.
32
D.
64
Solution
In a normal distribution, approximately 95% of the data lies within 2 standard deviations from the mean. SD = √16 = 4. Range = 20 ± 2*4 = 20 ± 8 = 12 to 28.
Q. A diet consists of 60% carbohydrates, 25% proteins, and 15% fats. If the total caloric intake is 2000 calories, how many calories come from fats? (2020)
A.
300
B.
400
C.
500

Calories from fats = 15% of 2000 = 0.15 * 2000 = 300 calories.
Q. A farmer has a rectangular field of dimensions 50 m by 30 m. If he wants to irrigate it with water from a river, how much water is needed to cover the field to a depth of 0.1 m? (2023)
A.
150 m³
B.
300 m³
C.
500 m³
D.
100 m³
Solution
Volume of water needed = Area × Depth = (50 m × 30 m) × 0.1 m = 150 m³.
Q. A food item contains 10 grams of carbohydrates, 5 grams of protein, and 2 grams of fat. How many total calories does this food item provide? (Carbohydrates = 4 cal/g, Protein = 4 cal/g, Fat = 9 cal/g) (2022)
