A) RS. 11.500
B) RS. 10.000
C) RS. 10,500
D) RS. 11.000
Correct Answer: B
Solution :
If the principal be Rs. P. then Amount \[=P\left( 1+\frac{{{R}_{1}}}{100} \right)\left( 1+\frac{{{R}_{2}}}{100} \right)\left( 1+\frac{{{R}_{3}}}{100} \right)\] \[\Rightarrow 12243\] \[=P\left( 1+\frac{5}{100} \right)\left( 1+\frac{6}{100} \right)\left( 1+\frac{10}{100} \right)\] \[\Rightarrow \] \[12243=P\left( 1+\frac{1}{20} \right)\left( 1+\frac{3}{50} \right)\left( 1+\frac{1}{10} \right)\] \[\Rightarrow \] \[12243=P\times \frac{21}{20}\times \frac{53}{50}\times \frac{11}{10}\] \[\Rightarrow \] \[P=\frac{12243\times 20\times 50\times 10}{21\times 53\times 11}\] =Rs.10000You need to login to perform this action.
