Given:

The series: 2, 6, 18, 54, ...

Formula Used:

The nth term of a geometric progression (GP) is given by: a_n = a × r^(n-1)

Where:

• a = first term
• r = common ratio
• n = term number

Calculation:

Find the common ratio (r).

r = Second term / First term = 6 / 2 = 3

Also, r = Third term / Second term = 18 / 6 = 3

The common ratio (r) = 3.

Identify the first term (a) and the term number (n).

First term (a) = 2

We need to find the 8^th number, so n = 8.

Calculate the 8^th term using the formula.

a₈ = a × r^(8-1)

a₈ = 2 × 3⁷

a₈ = 2 × (3 × 3 × 3 × 3 × 3 × 3 × 3)

a₈ = 2 × 2187

a₈ = 4374

∴ The 8^th number in the series is 4374.

Given:

Expression 1: -4 - (-10)

Expression 2: -10 - (-4)

Calculation:

First, calculate the value of the first expression:

-4 - (-10) = -4 + 10 = 6

Next, calculate the value of the second expression:

-10 - (-4) = -10 + 4 = -6

Now, find how much greater the first value is than the second value by subtracting the second value from the first value:

Difference = (Value of first expression) - (Value of second expression)

Difference = 6 - (-6)

Difference = 6 + 6

Difference = 12

∴ The value of -4 - (-10) is 12 greater than the value of -10 - (-4).

The logic followed here is:

Given:

Number = 175760

Formula used:

To make a number a perfect cube, all prime factors must appear in multiples of 3.

Prime factorization is used to identify and adjust the powers of prime numbers.

Calculation:

Step 1: Prime factorization of 175760

⇒ 175760 ÷ 2 = 87880

⇒ 87880 ÷ 2 = 43940

⇒ 43940 ÷ 2 = 21970

⇒ 10985 ÷ 5 = 2197

⇒ 2197 = 13 × 13 × 13 = 13³

So, 175760 = 2⁴ × 5 × 13³

Step 2: To make it a perfect cube:

• 2⁴: Extra 1 power (4 is not divisible by 3), so divide by 2¹
• 5¹: Not divisible by 3, so divide by 5¹
• 13³: Already a multiple of 3, keep as is

Step 3: Divide 175760 by (2 × 5) = 10

∴ The smallest number to divide 175760 to make it a perfect cube is 10.

Given:

Average temperature for Wednesday, Thursday, and Friday = 40 ºC

Average temperature for Thursday, Friday, and Saturday = 41 ºC

Temperature on Saturday = 42 ºC

Formula used:

Average = Sum of temperatures ÷ Number of days

Calculations:

Let Wednesday's temperature = W, Thursday's temperature = T, Friday's temperature = F.

From the first average:

⇒ (W + T + F) ÷ 3 = 40

⇒ W + T + F = 40 × 3 = 120

From the second average:

⇒ (T + F + Saturday's temperature) ÷ 3 = 41

⇒ T + F + 42 = 41 × 3 

⇒ T + F = 123 - 42 = 81

Substitute T + F = 81 into the first equation:

⇒ W + T + F = 120

⇒ W + 81 = 120

⇒ W = 120 - 81 = 39

∴ The temperature on Wednesday is 39 ºC.

The correct answer is option (2).

Given:

The average of 50 numbers = 38

Two numbers removed: 45 and 55

Calculation:

Sum of all numbers = 50 × 38

⇒ Sum of all numbers = 1900

Sum of removed numbers = 45 + 55

⇒ Sum of removed numbers = 100

New sum = 1900 - 100

⇒ New sum = 1800

New total count = 50 - 2

⇒ New total count = 48

New Average = 1800 / 48

⇒ New Average = 37.5

∴ The correct answer is option (4).

Given:

Principal (P) = ₹5,000

Simple Interest (SI) = ₹1,500

Given:

A sells a bicycle to B at a profit of 20%.

B sells it to C at a profit of 25%.

C pays ₹225 to A for it.

Formula used:

Selling Price (SP) = Cost Price (CP) × (1 + Profit Percentage/100)

For multiple transactions:

Final SP = Initial CP × (1 + Profit1/100) × (1 + Profit2/100)

Calculations:

Let the cost price to A be ₹x.

225 = x × (1 + 20/100) × (1 + 25/100)

⇒ 225 = x × 1.2 × 1.25

⇒ 225 = x × 1.5

⇒ x = 225 / 1.5

⇒ x = ₹150

∴ The cost price to A is ₹150, and the correct answer is option (1).

Given:

Selling Price (SP) = ₹2,850

Profit Percentage (P%) = 14%

Reduced Profit Percentage = 8%

Formula used:

Cost Price (CP) = \(\frac{SP}{1 + \frac{P%}{100}}\)

New Selling Price (SP) = CP × \((1 + \frac{Reduced\ P%}{100})\)

Calculation:

CP = \(\frac{2850}{1 + \frac{14}{100}}\)

⇒ CP = \(\frac{2850}{1 + 0.14}\)

⇒ CP = \(\frac{2850}{1.14}\)

⇒ CP = ₹2500

New SP = CP × \((1 + \frac{8}{100})\)

⇒ New SP = ₹2500 × \((1 + 0.08)\)

⇒ New SP = ₹2500 × 1.08

⇒ New SP = ₹2,700

∴ The correct answer is option (3).

Given:
