Formula used:

Class marks = (Lower limit + Upper limit)/2

Calculation:

The sum of the class marks of 90-120 and 120-150 = (90 + 120)/2 + (120 + 150)/2

⇒ 210/2 + 270/2 = 105 + 135 = 240

∴ The required result = 240

Given:

(1) Altimeter → An altimeter is a device that measures altitude.

(2) Barometer → A barometer is a scientific instrument used to measure atmospheric pressure.

(3) Dynamometer → A dynamometer is a device that measures force, torque or power.

(4) Thermometer → A thermometer measures the temperature of a person or premises indicating the intensity of heat or cold.

The logic follows here is: All these are measuring instruments.

Hence, measuring instruments is the correct answer.

a³ - b³ = (a - b)(a² + ab + b²)

(2m)³ - n³ = (2m - n)(4m² + 2mn + n²)

Given:

35% of x = 140

Calculation:

35% of x = 140

⇒ 35/100 × x = 140

⇒ x = 140 × 100/35

∴ x = 400

Additional Information

Given:

Present population of a town = 50000

Increasing rate of the population per year = 4%

Calculation:

Population of the town at the end of one year = 50000 + 50000 × 4/100 = 52000

Population of the town at the end of two years = 52000 + 52000 × 4/100 = 54080

∴ The required population = 54080

Alternate MethodEffective rate of increase in population: a + a + a × a/100

⇒ 4 + 4 + 4 × 4/100 = 8.16%

Total population after 2 years = 50000 × (100% + 8.16%)

⇒ 54080

Given: 111, 90, 71, 54, ?

Reason: The difference in odd numbers is decreasing as shown in the diagram:

Given:

Radius of cylinder and cone = r

Height of cylinder and cone = h

Formulas used:

Volume of cylinder = πr²h

Volume of cone = 1/3 × πr²h

Calculation:

∴ Volume of cylinder/Volume of Cone = πr2h/1/3 × πr2h

⇒ 3/1 = 3 : 1

  • It is explosive in concentrated amounts and can react with many chemical compounds.
  • Most ozone (about 90%) is found in the stratosphere, a region that begins about 10-16 kilometers (6-10 miles) above Earth’s surface.
  • Further, most ozone resides in the stratosphere in “ozone layer.”

Additional Information

• The ozone layer covers the entire planet and protects life on earth by absorbing harmful ultraviolet-B (UV-B) radiation from the sun.
• When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation.
• It damages vegetation and ecosystems by inhibiting the ability of plants to open the microscopic pores on their leaves to breathe.
• It also interferes with the photosynthesis process by reducing the amount of carbon dioxide the plants can process and release as oxygen.

The correct answer is Camels are used for transportation in deserts.

Calculation:

Sum of the number of laptops and mobiles sold = 500 + 600 = 1100

Sum of the number of Radio, Tvs and watches sold = 100 + 300 + 200 = 600

⇒ The difference in the no of laptops and mobiles sold in comparison to the no of other products = 1100 - 600 = 500

∴ The required result = 500

Given:

x ∝ y

⇒ x = ky [k is a constant]

Calculation:

When x = 10; y = 15

⇒ 10 = 15k

⇒ k = 2/3

Option A: For x = 15; y = 20

⇒ 15 = 20k

⇒ k = 3/4 ≠ 2/3

Option B: For x = 8; y = 12

⇒ 8 = 12k

⇒ k = 2/3

Option C: For x = 25; y = 37.5

⇒ 25 = 37.5k

⇒ k = 25/37.5 = 2/3

Option D: For x = 2; y = 3

⇒ 2 = 3k

⇒ k = 2/3

∴ All except option A, satisfy the value of k. So 15, 20 cannot be the corresponding values of x and y.

Logic: Sum of Positional Values.

Hence, 126 is the correct answer.
