Answer:

दिलेल्या रकमेवर ₹ 129.20 चक्रवाढ व्याज होते.

Step-by-step-explanation:

आपल्याला दिलेले आहे की,

मुद्दल ( P ) = ₹ 500

व्याजाचा दर ( R ) = 10 %

कालावधी ( N ) = 2 वर्षे 6 महीने = 2 ½ वर्षे = 2.5 वर्षे

आपल्याला चक्रवाढ व्याज ( C. I. ) काढायचे आहे.

\displaystyle{\pink{\sf\:C\:.\:I\:.\:=\:P\:\left(\:1\:+\:\dfrac{R}{100}\:\right)^N\:-\:P}}

\displaystyle{\implies\sf\:C\:.\:I\:.\:=\:500\:\left(\:1\:+\:\dfrac{1\cancel{0}}{10\cancel{0}}\:\right)^{2.5}\:-\:500}

\displaystyle{\implies\sf\:C\:.\:I\:.\:=\:500\:\left(\:1\:+\:\dfrac{1}{10}\:\right)^{2.5}\:-\:500}

\displaystyle{\implies\sf\:C\:.\:I\:.\:=\:500\:\left(\:\dfrac{10\:+\:1}{10}\:\right)^{2.5}\:-\:500}

\displaystyle{\implies\sf\:C\:.\:I\:.\:=\:500\:\times\:\left(\:\dfrac{11}{10}\:\right)^{2.5}\:-\:500}

\displaystyle{\implies\sf\:C\:.\:I\:.\:=\:500\:\times\:\left(\:\dfrac{11}{10}\:\right)^2\:\times\:\left(\:\dfrac{11}{10}\:\right)^{\dfrac{1}{2}}\:-\:500}

\displaystyle{\implies\sf\:C\:.\:I\:.\:=\:5\cancel{00}\:\times\:\dfrac{11}{1\cancel{0}}\:\times\:\dfrac{11}{1\cancel{0}}\:\times\:\sqrt{\dfrac{11}{10}}\:-\:500}

\displaystyle{\implies\sf\:C\:.\:I\:.\:=\:5\:\times\:11\:\times\:11\:\times\:\sqrt{\dfrac{11}{10}}\:-\:500}

\displaystyle{\implies\sf\:C\:.\:I\:.\:=\:55\:\times\:11\:\times\:\dfrac{\sqrt{11}}{\sqrt{10}}\:-\:500}

\displaystyle{\implies\sf\:C\:.\:I\:.\:=\:605\:\times\:\cancel{\dfrac{3.31}{3.16}}\:-\:500}

\displaystyle{\implies\sf\:C\:.\:I\:.\:=\:605\:\times\:1.04\:-\:500}

\displaystyle{\implies\sf\:C\:.\:I\:.\:=\:629.2\:-\:500}

\displaystyle{\implies\underline{\boxed{\red{\sf\:C\:.\:I\:.\:\approx\:129.20\:Rs}}}}

∴ दिलेल्या रकमेवर ₹ 129.20 चक्रवाढ व्याज होते.
