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

X and Y are children of Z.

Z is the father of X

but Y is not son of Z,

جب اس کا وہ بیٹا نہیں ہے تو یقینن بیٹی ہے

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.

Explanation

• Tomorrow is one day ahead.
• The day after tomorrow is two days ahead.
• The day after the day after tomorrow is three days ahead.

• Thursday (3 days ahead) -> Wednesday (2 days ahead) -> Tuesday (1 day ahead) -> Monday (today).

Explanation

Let's break it down step by step:

1. Four to the left of G:

The alphabet sequence is A B C D E F G.

Four positions to the left of G would be C (G -> F -> E -> D -> C).

2. Immediately to the left of C:

The letter immediately to the left of C is B.

3. Three to the right of B:

Starting from B and moving three positions to the right: B -> C -> D -> E.

So, the letter three positions to the right of B is E.

Explanation

To find the total number of handshakes, we use the combination formula since each member shakes hands with every other member exactly once before and after the meeting.

Number of members = 12

Handshakes before the meeting = 12C2 = (12 × 11) / 2 = 66

Handshakes after the meeting = 66

Total handshakes = 66 + 66 = 132
