Option 1: Rs. 7568.50

Option 2: Rs. 6220.80

Option 3: Rs. 6516.80

Option 4: Rs. 5128.50

Team Careers360 15th Jan, 2024

Correct Answer: Rs. 6220.80


Solution : Using the formula,
$A$ = $P(1+\frac{r}{100})^{t}$ 
Given that $P$ = Rs. 3000, $A$ = Rs. 4320, and $t$ = 2 years.
⇒ 4320 = 3000$(1 + \frac{r}{100})^{2}$
⇒ $(1 + \frac{r}{100})^{2}$ = $(\frac{4320}{3000})$
⇒ $(1 + \frac{r}{100})$ = $(\frac{4320}{3000})^{\frac{1}{2}}$
After 4 years, $t$ =
