Correct Answer: (1)
Solution: (1)
When $T=15%$
S.I. $=\frac{6000 \times 15 \times 3}{100}$ $=$ Rs. 2700
C.I. $=P[(1+\frac{R}{100})^{T}-P]$
$=6000[(1+\frac{20}{100})^{2}-1]$
$=6000[(1+\frac{1}{5})^{2}-1]$
$=6000(\frac{36}{25}-1)$
$=6000 \times \frac{11}{25}=$ Rs. 2640
$\therefore$ Difference $=$ Rs. $(2700-2640)$ $=$ Rs. 60
