The complete pattern will be:

Hence, the correct answer is "Option 3".

The logic followed here is:

River ∶ Ocean - A river meets into the ocean.

Similarly,

Street ∶ Road - The Streat meets into the Road.

Hence, the correct answer is "Option 3".

Shortcut Trick

Let initial mixture = 100 units ⇒ Milk = 20 units, Water = 80 units.

Amount of water added = 80 units (equal to original water).

New water = 80 + 80 = 160 units, Total new mixture = 100 + 80 = 180 units.

Percentage of water = (160 ÷ 180) × 100 ≈ 89%.

∴ The correct answer is 89%.

Alternate Method

Given:

Percentage of milk in the initial mixture = 20%

Amount of water added = Initial amount of water in the mixture

Formula Used:

Percentage of component = (Amount of component ÷ Total mixture) × 100

Calculations:

Let the initial volume of the mixture be 100 units.

⇒ Initial Milk = 20% of 100 = 20 units

⇒ Initial Water = 100 − 20 = 80 units

⇒ Amount of water added = Initial water = 80 units

⇒ Total water in new mixture = 80 + 80 = 160 units

⇒ Total volume of new mixture = 100 + 80 = 180 units

⇒ Percentage of water in final mixture = (160 ÷ 180) × 100

⇒ (8 ÷ 9) × 100 = 88.88%

⇒ Approximating to nearest whole number = 89%

∴ The correct answer is 89%.

Rule of Alligation

Used to find the ratio in which two mixtures of known concentrations are mixed to get a desired concentration. Ratio = (d − m) : (m − c).

Percentage Change

When a new component is added, the total base of the mixture changes, affecting the percentage of all components. New % = (New Value ÷ New Total Base) × 100.

Replacement Formula

If 'y' units of a mixture of volume 'x' are replaced by an equal amount of water 'n' times, Final Amount of pure liquid = Initial Amount × (1 − y/x)ⁿ.

The logic followed here is:

So, 4^th figure will complete the pattern.

Hence, the correct answer is "Option 4".

Given:

A train running at a speed of 54 km/h crosses a telegraph pole in 9 seconds.

Concept used:

Distance = Speed × Time

1m/s = 18/5 km/h

While a train crosses a telegraph pole, it crosses its own length.

Calculation:

54 km/h = 54 ÷ 18/5

⇒ 15m/s

Length of the train = 15 × 9 

⇒ 135m

∴ The length of the train is 135m.
