Show answer & explanation
Correct answer: B
Values from the chart:
B1 = ₹1850
B2 = ₹2075
B3 = ₹2800
B4 = ₹2250
B5 = ₹2400
B6 = ₹1600
Check each statement:
Statement I: Claims B2 is 5.25% less than B5. Calculation: (2400 − 2075) / 2400 × 100 = 325 / 2400 × 100 ≈ 13.54%. So statement I is false.
Statement II: Claims B4 is 6.25% less than B5. Calculation: (2400 − 2250) / 2400 × 100 = 150 / 2400 × 100 = 6.25%. So statement II is true.
Statement III: Claims the average is ₹2262.50. Sum = 1850 + 2075 + 2800 + 2250 + 2400 + 1600 = 12,975. Average = 12,975 / 6 = ₹2,162.50. So statement III is false.
Final answer:
Only statement II is correct.
