Question

Aditya invested certain amount in two different schemes $A$ and $B$. Scheme $A$ offer $S.I.@$ $12\%\text{p.a}$. and scheme $B$ offer $C.I.@$ $10\%\text{p.a}$ interest accrued on the amount invested in schemes $A$ in $2$ years was $\text{Rs.}3600$ and the total amount invested was $\text{Rs.}35000$. What was the interest accrued on the amount invested in scheme $B$?

• A. $\text{Rs.}4500$
• B. $\text{Rs.}4200$
• C. $\text{Rs.}4000$
• D. Cannot be determined

Answer 1

Answer: (B)

$\text{Rs.}4200$

Scheme A: SI @ $12pcpa$

Scheme B: CI @ $10pcpa$

$T=2\text{years}$

$P=\text{Rs.}35,000$

$SI=\frac{P\times R\times T}{100}$

$3600=\frac{p\times 12\times 2}{100}$

$P=\text{Rs.}15,000$

Investment in other scheme $=\text{Rs.}20,000$

$CI=A-P$

$A=20,000{(1+\frac{10}{100})}^2$

$A=\text{Rs.}24,200$

Interest increased in scheme $B=CI=A-P$

$=\text{Rs.}(24,000-20,000)$

$=\text{Rs.}4200$
