A) Rs. 2580
B) Rs. 2400
C) Rs. 2529
D) Rs. 3600
Correct Answer: D
Solution :
Let the sum be Rs. x. \[\frac{x\times 5\times 15}{100\times 12}=\frac{x\times 4\times 8}{100\times 12}=129\] \[\Rightarrow \] \[\frac{x}{100\times 12}(75-32)=129\] \[\Rightarrow \] \[x=\frac{129\times 1200}{43}=Rs.\,3600\]You need to login to perform this action.
