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:

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, ?

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.
