A) Rs. 3794
B) Rs. 3714
C) Rs. 4612
D) Rs. 4634
Correct Answer: D
Solution :
(d): To find rate of interest A = 1.8 P \[1.8p=p\left[ 1+\frac{8r}{100} \right]\] \[\Rightarrow 1.8-1=\frac{8r}{100}\] \[\Rightarrow 0.8=\frac{8r}{100}\] \[\Rightarrow r=10%\] C.I on 14000/- \[C.I=14000\left[ {{\left( 1+\frac{10}{100} \right)}^{3}}-1 \right]\] \[=14000\times \left[ {{1.1}^{3}}-1 \right]\] \[=14000\times 0.331\] \[=Rs.4634/-.\]You need to login to perform this action.
