Question

Directions: Given below are two quantities named I and II. Based on the given information, you have to determine the relation between the two quantities. You should use the given data and your knowledge of Mathematics to choose among the possible answers.

Quantity I: Three numbers are in the ratio 7 : 21 : 25.Their average is 53. Find the largest number.

Quantity II: 34
1. Quantity I ˃ Quantity II
2. Quantity I ˂ Quantity II
3. Quantity I ≤ Quantity II
4. Quantity I ≥ Quantity II
5. Quantity I = Quantity II

Answer 1

Correct Answer - Option 1 : Quantity I ˃ Quantity II

Quantity I:

Let the numbers be 7x, 21x and 25x

⇒ (7x + 21x + 25x) / 3 = 53

⇒ (53x / 3) = 53

⇒ x = (53 × 3) / 53

⇒ x = 3

Largest number is 75 (i.e. 25 × 3)

Quantity II: 34

∴ Quantity I ˃ Quantity II
