A certain sum will amount to ₹ $12,100$ in $2$ years at $10 \%$ per annum of compound interest, interest being compounded annually. The sum is (In ₹)

₹ $6,100$ was partly invested in Scheme $A$ at $10 \%$ p.a. compound interest (compounded annually) for $2$ years and partly in Scheme $B$ at $10 \%$ p.a. simple interest for $4$ years. Both the schemes pay equal interests. How much was invested (In ₹) in Scheme $A$?

The difference between simple interest and compound interest (In ₹) on ₹ $1250$ for $2$ years at $4 \%$ $p.a.$ is

The difference of compound interest (In ₹) on ₹ $800$ for $1$ year at $20 \%$ per annum when compounded half-yearly and quarterly is

Which of the statement given below are sufficient to answer the following question.

What is the rate of interest $p.c.p.a.$ on the amount of $Rs. 15000$ taking loan?

($I$) The difference between $C.I. \& S.I.$ is $Rs. 170$

($II$) The $S.I.$ of $2$ years is $Rs. 2500$

What would would be the $C.I.$ obtained on an amount of $Rs. 4800$ at the rate of $5$ $p.c.p.a$ for $3$ years (In $Rs.$)?
