Question:

Find the compound interest on Rs $10,000$ at $20\%$ per annum for $1$ year, compounded half-yearly. / Rs $10,000$ पर $20\%$ वार्षिक दर से $1$ वर्ष का चक्रवृद्धि ब्याज ज्ञात कीजिए, जबकि ब्याज अर्धवार्षिक संयोजित होता है।

1.
Rs $2,000$ / Rs $2,000$
2.
Rs $2,050$ / Rs $2,050$
3.
Rs $2,100$ / Rs $2,100$
4.
Rs $2,200$ / Rs $2,200$

Correct Answer: Rs $2,100$ / Rs $2,100$

Half-yearly rate $= 20/2 = 10\%$, periods $= 2$. Amount $= 10000 \times (1.10)^2 =$ Rs $12,100$. Compound interest $= 12100 - 10000 =$ Rs $2,100$. / अर्धवार्षिक दर $= 20/2 = 10\%$, अवधि $= 2$। मिश्रधन $= 10000 \times (1.10)^2 =$ Rs $12,100$। चक्रवृद्धि ब्याज $= 12100 - 10000 =$ Rs $2,100$।
