Explanation

The pattern is reversing the digits:

PEACH → HCAEP

26541 → 14562

Explanation

Let's denote the number of items Abdul has as x.

Akram has one and a half times as many as Abdul:

Akram = 1.5x

Aslam has one and a half times as many as Akram:

Aslam = 1.5 * 1.5x = 2.25x

The total number of items is 76:

x + 1.5x + 2.25x = 76

4.75x = 76

x = 16

Now, let's find the number of items each has:

Abdul: x = 16

Akram: 1.5x = 1.5 * 16 = 24

Aslam: 2.25x = 2.25 * 16 = 36

So, Aslam has 36, Akram has 24, and Abdul has 16.

Explanation

The phrase "all but 10 died" means that 10 goats are left alive.

Explanation

Let's calculate Akram's current age:

Akram's age = 2 × Aslam's age

= 2 × 11

= 22 years

The difference in their ages is:

22 - 11 = 11 years

When Akram is 50 years old, Aslam will be:

50 - 11 = 39 years old

Explanation

To find the number of handshakes, we can use the combination formula:

nC2 = n(n-1)/2

where n is the number of members (13).

For before the meeting: 13C2 = 13(12)/2 = 78

For after the meeting: 13C2 = 13(12)/2 = 78

Total handshakes = 78 + 78 = 156

Explanation

The question asks how many cookies Ali can eat in his completely empty stomach.

The answer is 1 because after eating the first cookie, his stomach won't be empty anymore.

Explanation

Given the series is:

1, 2, 2, 4, 4, 6, 8, 8, 16

Let's break it down:

Powers of 2 are interspersed with repetitions: 1 (2^0), 2 (2^1), 2, 4 (2^2), 4, 8 (2^3), 8, 16 (2^4)

If the pattern continues with repetitions after powers of 2:

The next number would logically be 16 (a repetition of the last number, 16).

Explanation

E: This is the leftmost node in the in-order sequence. It becomes the root in the preorder traversal.

A: The next node after E is its left child. So, A is the left child of E.

C: Moving further, C is the right child of A.

K: K is the right child of C.

F: F is the right child of K.

H: H is the right child of F.

D: D is the left child of F.

B: B is the left child of A.

G: Finally, G is the right child of B.

Putting it all together, we get the preorder traversal: FAEKCDHGB.
