A) Rs. 65650
B) Rs. 65065
C) Rs. 6565
D) Rs. 6500
Correct Answer: D
Solution :
Let the sum be Rs. x. Then, \[CI=x{{\left( 1+\frac{10}{100} \right)}^{2}}-x=\frac{21x}{100}\] \[SI=\frac{x\times 100\times 2}{100}=\frac{x}{5}\] \[\therefore \] \[CI-SI=\frac{21x}{100}-\frac{x}{5}=\frac{x}{100}\] \[\therefore \] \[\frac{x}{100}=65\]\[\therefore \]\[x=6500\] Hence, the sum is Rs. 6500You need to login to perform this action.
