Given:

  • Total amount distributed = Rs 624

  • Ratio of distribution among three friends = ½ : ⅓ : ¼

Concept Used:

The ratio ½ : ⅓ : ¼ needs to be converted into a common form by finding the least common denominator (LCD).

After converting, the ratio becomes integers that can be used directly for calculations.

The formula to calculate the share is: Share = (Ratio of friend / Sum of ratios) × Total amount

Calculation:

Step 1: Convert the ratio ½ : ⅓ : ¼ into integers.

The LCD of 2, 3, and 4 is 12.

⇒ Multiply each fraction by 12:   ½ × 12 = 6   ⅓ × 12 = 4   ¼ × 12 = 3

∴ The ratio becomes 6 : 4 : 3.

Step 2: Calculate the sum of the ratios.

⇒ Sum of ratios = 6 + 4 + 3 = 13.

Step 3: Calculate the share of the third friend (ratio = 3).

⇒ Share of third friend = (3 / 13) × 624

⇒ Share = (3 × 624) / 13

⇒ Share = 1872 / 13

⇒ Share = Rs 144

Step 4: Verify the correct answer.

∴ The share of the third friend is Rs 144.

Conclusion:

Hence, the correct answer is Option 4 (Rs 144).
