Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. increase by 1%.
Let the original number = 100
New number after the increase = 100 + 44 = 144
Final number after the decrease = (7/10) × 144 = 100.8
Net increase = 100.8 - 100 = 0.8% = 1% (approx)
Hence, the net percentage increase in the original number is 1%.
