दिया गया है:

मूलधन (P) = 44500 रुपये

समय (T) = 2 वर्ष।

ब्याज दर (R) = \(\dfrac{20}{4} = 5\%\).

प्रयुक्त सूत्र:

चक्रवृद्धि ब्याज (C.I.) = \(P\times\bigg(1+ \dfrac{R}{100} \bigg)^2 -P\)

जहाँ C.I. = चक्रवृद्धि ब्याज।

गणना:

C.I. = \(44500\times\bigg(1+ \dfrac{5}{100} \bigg)^2 - 44500\) = \(44500\times\dfrac{21}{20}\times\dfrac{21}{20}- 44500 = 4561.25\)

इसलिए उत्तर "4561.25" है।
