Given:

The average age of A, B, and C is 45 years.

The average age of A, C, and D is 51 years.

The age of D is 56 years.

Formula Used:

Average = (Sum of quantities) / (Number of quantities)

Calculations:

According to the question:

Sum of ages of A, B, and C = 45 × 3 = 135 years

Sum of ages of A, C, and D = 51 × 3 = 153 years

Given that the age of D is 56 years, we can find the sum of ages of A and C:

Sum of ages of A and C = 153 - 56 = 97 years

Now, we know the sum of ages of A, B, and C is 135 years. Therefore, we can find the age of B:

Age of B = 135 - 97 = 38 years

∴ The age of B is 38 years.

Given:

Sequence: 1, 5, 14, 30, 55, ...

We need to find the 10^th term.

Pattern Analysis:

Observing the differences between consecutive terms:

5 - 1 = 4

14 - 5 = 9

30 - 14 = 16

55 - 30 = 25

The differences are: 4, 9, 16, 25, ...

These are squares of consecutive numbers: 2², 3², 4², 5², ...

Formula used:

T_n = T_n-1 + n²

Using this pattern, calculating up to the 10^th term:

6^th term = 55 + 6² = 91

7^th term = 91 + 7² = 140

8^th term = 140 + 8² = 204

9^th term = 204 + 9² = 285

10^th term = 285 + 10² = 385

Given:

Three given terms: st⁵, s² t³, s³ t²

We need to find the fourth proportional.

Formula used:

If a, b, c, and d are in proportion, then:

a : b = c : d

⇒ d = (b × c) / a

Calculation:

Here, a = st⁵, b = s²t³, c = s³t²

Fourth proportional (d) = (b × c) / a

⇒ d = (s²t³ × s³t²) / (st⁵)

⇒ d = (s⁽²⁺³⁾ t⁽³⁺²⁾) / (st⁵)

⇒ d = (s⁵ t⁵) / (st⁵)

⇒ d = s^(5-1) t^(5-5)

⇒ d = s⁴ t⁰

⇒ d = s⁴

Given:

Upstream distance = 12 km, Downstream distance = 20 km

Time taken = 4 hours

Upstream distance = 18 km, Downstream distance = 10 km

Time taken = 4 hours

Formula used:

Speed in still water (S) and speed of stream (R) are given by:

Upstream speed = S - R

Downstream speed = S + R

Time = Distance / Speed

Calculation:

Using time equation for first case:

⇒ \(\dfrac{12}{S - R} + \dfrac{20}{S + R} = 4 \)

Using time equation for second case:

⇒ \(\dfrac{18}{S - R} + \dfrac{10}{S + R} = 4 \)

Let \(x = \dfrac{1}{S - R} \) and \(y = \dfrac{1}{S + R}\), then:

⇒ \(12x + 20y = 4 \)

⇒ \(18x + 10y = 4 \)

Multiplying first equation by 3 and second by 2:

⇒ \(36x + 60y = 12 \)

⇒ \(36x + 20y = 8 \)

Subtracting:

⇒ \(40y = 4 \) ⇒ \(y = \dfrac{1}{10}\)

Substituting in first equation:

⇒ \(12x + 20 \times \dfrac{1}{10} = 4 \)

⇒ \(12x + 2 = 4 \) ⇒ \(x = \dfrac{1}{6}\)

Since \(x = \dfrac{1}{S - R}\) and \(y = \dfrac{1}{S + R}\):

⇒ \(S - R = 6 \) and \(S + R = 10\)

Adding equations:

⇒ \(2S = 16 \) ⇒ \(S = 8 \)

∴ The speed in still water is 8 km/h.
