Show answer & explanation

Correct answer: C

Solution:

  1. Find total and average percentage spent on food across the five years: 21% + 13% + 20% + 10% + 40% = 104%. Average food% = 104 ÷ 5 = 20.8%.

  2. Convert average food% to money: 20.8% of ₹500,000 = 0.208 × 500,000 = ₹1,04,000.

  3. Find total and average percentage saved across the five years: 35% + 15% + 50% + 17% + 35% = 152%. Average saving% = 152 ÷ 5 = 30.4%.

  4. Convert average saving% to money: 30.4% of ₹500,000 = 0.304 × 500,000 = ₹1,52,000.

  5. Compute required percentage: (average money spent on food ÷ average money saved) × 100 = (1,04,000 ÷ 1,52,000) × 100 ≈ 68.42% ≈ 68%.

Answer: 68%.
