प्रयुक्त सूत्र

एकल समतुल्य वृद्धि = x + y + [(x × y)/100]

एकल समतुल्य कमी = x + y - [(x × y)/100]

गणना

प्रत्येक 30% की एकल समतुल्य वृद्धि = 30 + 30 + [(30 × 30)/100]

= 30 + 30 + 9 = 69%

प्रत्येक 30% की एकल समतुल्य कमी = 30 + 30 - [(30 × 30)/100]

= 51%

अभीष्ट प्रतिशत = [(69 - 51)/51] × 100

= 18/51 × 100 = 35.29%

उत्तर 35.29% है।
