Explanation
GP series = 4, 8, 16, 32, ... 512.
FORMULA USED:
Tn = ar(n-1)
SOLUTION:
GP series = 4, 8, 16, 32, ... 512.
Tn = ar(n-1)
⇒ 512 = 4 × 2(n - 1)
⇒ 128 = 2(n - 1)
⇒ 27 = 2(n - 1)
Now comparing powers we obtain;
⇒ n - 1 = 7
⇒ n = 8

Explanation
Total students = 26
Students who like football = 21
Students who like cricket = 14
Let x be the number of students who like both football and cricket.
Using the formula:
(Football ∪ Cricket) = Football + Cricket – Both
So,
26 = 21 + 14 – x
26 = 35 – x
x = 35 – 26
x = 9

Explanation
The pattern of the series appears to be square numbers:
- 1 = 1^2
- 9 = 3^2
- 25 = 5^2
- 49 = 7^2
- 81 = 9^2
- 121 = 11^2
So, the correct completion of the series would be:
1, 9, 25, 49, 81, 121

Explanation
Percentage = (Blue pens / Total pens) × 100 = (9 / 180) × 100 = 5%
اگر ایک ٹرین 180 کلومیٹر فی گھنٹہ چلتی ہے تو وہ 8 گھنٹے میں کتنا فاصلہ طے کرے گی؟

اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
If a train runs 180 km per hour, how much distance will it travel in 8 hours = 1440
Speed of train v=180 km/h
Time taken t = 8 h
So, distance covered by train D = v t
D=180 × 8
=1440 km
- 44 years

- 28 years
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The difference in their ages is 33 years, so:
7x - 4x = 33
3x = 33
x = 11
Now, we can find Zaid's age:
Zaid's age = 4x
= 4 × 11
= 44 years
