A) Rs. 15000
B) Rs. 10500
C) Rs. 10050
D) Rs. 10000
Correct Answer: A
Solution :
Let the total income of Neelam is Rs. x. Expenditure on house rent \[=x\times \frac{20}{100}\]= Rs. \[\frac{x}{5}\] Expenditure on house hold \[=\left( x-\frac{x}{5} \right)\times \frac{70}{100}\] \[=\frac{4x}{5}\times \frac{70}{100}\]= Rs. \[\frac{14x}{25}\] According to the question, \[\frac{x}{5}+\frac{144}{25}+3600=x\] \[\Rightarrow \] \[x-\frac{x}{5}-\frac{14x}{25}=3600\] \[\Rightarrow \] \[\frac{25x-5x-14x}{25}=3600\] \[\Rightarrow \] \[\frac{6x}{25}=3600\] \[\therefore \] \[x=\frac{3600\times 25}{6}\]= Rs. 15000You need to login to perform this action.
