A) Rs. 2540
B) Rs. 3430
C) Rs. 3260
D) Rs. 3380
Correct Answer: B
Solution :
Let each instalment be Rs. x. Then \[\frac{x}{\left( 1+\frac{50}{3\times 100} \right)}+\frac{x}{{{\left( 1+\frac{50}{3\times 100} \right)}^{2}}}+\frac{x}{{{\left( 1+\frac{50}{3\times 100} \right)}^{3}}}\] \[=7620\] or \[\frac{6x}{7}+\frac{36x}{49}+\frac{216x}{343}=7620\] \[294x+252x+216x=7620\times 343\] or \[x=\frac{7620\times 343}{762}=3430\] \[\therefore \] Amount of each instalment\[=Rs.\text{ }3430\].You need to login to perform this action.
