A) 650
B) 630
C) 625
D) 640
Correct Answer: C
Solution :
Let the sum be Rs. x \[\therefore \] \[x\left[ {{\left( 1+\frac{4}{100} \right)}^{2}}-1 \right]-\frac{x\times 4\times 2}{100}=1\] \[\Rightarrow \] \[x\left[ \frac{16}{10000}+\frac{2\times 4}{100} \right]-\frac{x\times 4\times 2}{100}=1\] \[\Rightarrow \] \[\frac{16x}{10000}=1\] \[\Rightarrow \] \[x=\frac{10000}{16}=625\] So, the sum = Rs. 625You need to login to perform this action.
