Question : If the difference between the compound interest and simple interest at 17%; on a sum of money for 2 years (compounded annually) is INR 433.50, then the compound interest (in INR) is:
Option 1: 2,735.50
Option 2: 2,500
Option 3: 5,100
Option 4: 5,533.50
Correct Answer: 5,533.50
Solution : Given: Difference = INR 433.50 Rate = 17% Time = 2 years We know that, $D=P(\frac{r}{100})^2$, where $D$ = Difference between CI and SI, $P$ = Principal, $r$ = Rate of interest ⇒ $433.50=P(\frac{17}{100})^2$ ⇒ $433.50=P\times\frac{17}{100}\times\frac{17}{100}$ ⇒ $P=15000$ Now, $CI= P((1+\frac{R}{100})^{T}-1)$ $= 15000((1+\frac{17}{100})^{2}-1)$ $= 15000((\frac{117}{100})^{2}-1)$

Question : The discount on a certain sum of money, due at the end of $2\frac{1}{4}$ years at $2\frac{2}{3}$% p.a. is Rs. 78 find the sum.
Option 1: Rs. 1,278
Option 2: Rs. 1,300
Option 3: Rs. 1,378
Option 4: Rs. 1,400
Correct Answer: Rs. 1,300
Solution : Rate = $2\frac{2}{3}$% Time = $2\frac{1}{4}$ years Interest = Rs. 78 Let the Principal be $x$. Simple Interest = $\frac{\text{Principal × Rate × Time}}{100}$ $⇒78=\frac{x×2\frac{2}{3}×2\frac{1}{4}}{100}$ $⇒78=x×\frac{8}{3}×\frac{9}{4}×\frac{1}{100}$ $\therefore x = 1300$ Hence, the correct answer is Rs. 1,300.
