Correct Answer - Option 2 : 250

**Given:**

Ratio = 5: 2

Difference = 150

**Calculation:**

Difference between ratios = 5 – 2

⇒ Difference between ratio = 3 units

⇒ 3 units = 150

⇒ 1 unit = 50

⇒ Largest of number = 5 × 50

⇒ Largest number = 250

**Alternate method:**

Let numbers be 2X and 5X

⇒ 5X – 2X = 150

⇒ 3X = 150

⇒ X = 50

⇒ Largest of number = 50 × 5

**∴ largest of two numbers is 250**
