दिया गया है:

10% की क्रमागत तीन बट्टा= एकल बट्टा ?

प्रयुक्त सूत्र:

उत्तरोत्तर बट्टा = X + Y -

\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)

जहाँ X = प्रथम बट्टा

Y = द्वितीय बट्टा

गणना:

10% और 10% का प्रथम बट्टा = 10 + 10 - 

\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\) = 20 -1 = 19%​

19% और 10% का द्वितीय अंतिम बट्टा = 19 + 10 -  

\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)

= 29 - 1.9 = 27.1%​​​​ ​​ 

 ∴ 10% की क्रमागत तीन बट्टा 27.1% की एकल छूट के समतुल्य है।
