Justice Ali Nawaz Chowhan was appointed Chief Justice of The Gambia in March 2014.

Explanation

The pattern appears to be a repeating sequence of:

-2, -2, +3, +3, -4, -4

15 (-2) = 13

13 (-2) = 11

11 (+3) = 14

14 (+3) = 17

17 (-4) = 13

Explanation

We know that the difference of their squares is 84, so we can write the equation:

(x+2)^2 - x^2 = 84

Expanding the equation, we get:

x^2 + 4x + 4 - x^2 = 84

Simplifying the equation, we get:

4x + 4 = 84

Subtracting 4 from both sides, we get:

4x = 80

Dividing both sides by 4, we get:

x = 20

So, the two consecutive even numbers are 20 and 22.

The sum of these numbers is:

20 + 22 = 42

Explanation

"To take a leaf out of someone's book" means to imitate someone in a particular way.

Usually, it involves adopting their successful methods or behaviors.

It implies learning from others' experiences to improve oneself.

Explanation

Convert the speed of the train from km/hr to m/s:

45 km/hr = 45 × 1000 m / 3600 s = 12.5 m/s

The train crosses the bridge in 30 seconds, so the total distance covered is the length of the train plus the length of the bridge. Let's call the length of the bridge "x". Then, the total distance = 130 m (train length) + x.

Since the train crosses the bridge in 30 seconds, we can use the formula:

Distance = Speed × Time

Substitute the values:

130 m + x = 12.5 m/s × 30 s

Simplify the equation:

130 m + x = 375 m

Subtract 130 m from both sides:

x = 245 m

So, the length of the bridge is 245 m.

Explanation

Since the square has four equal sides, the distance covered in one side can be found by dividing the total distance covered (8 km) by 4 (the number of sides):

8 km ÷ 4 = 1 km

So, the length of one side of the square ground is 1 km.
