Explanation
To compare the ratios, we can convert them to fractions and then decimals:
7:15 = 0.4667
15:23 = 0.6522
21:29 = 0.7241
The largest ratio is 21:29.

اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
To find speed, convert the time to hours and distance to kilometers:
Time = 2 minutes 30 seconds = 2.5 minutes = 2.5/60 = 1/24 hours
Distance = 750 meters = 0.75 kilometers
Speed = Distance / Time = 0.75 / (1/24) = 0.75 x 24 = 18 km/hr

اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Let C's age be x years. Then, B's age = 2x years. A's age = (2x + 2) years.
∴ (2x + 2) + 2x + x = 27
⇒ 5x = 25
⇒ x = 5.
Hence, B's age = 2x = 10 years.
- 2 is ordinate and 4 is abscissa
- 2 is abscissa and 4 is ordinate
- 2 and 4 both are abscissa
- None of these

Explanation
This series follows the pattern of a "Perfect cube root".Solution:
8 = It is the perfect cube of 2.
27 = It is the perfect cube of 3.
64 = It is the perfect cube of 4.
100 = It is not a perfect cube of any number.
125 = It is the perfect cube of 5.
216 = It is the perfect cube of 6.
343 = It is the perfect cube of 7.
Hence, the correct answer is "100".
