Anubhav spent 14% of his income on electricity bills, 28% on rent and 18% on shopping. If \(\frac{1}{4}\)th of the remaining amount is ₹5120, how much did he spend on electricity bills?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → ₹7168
The given ₹5120 is a part of what is left after the three expenses, so first find what percentage of the income is left, then the income, then 14% of it.
Spent \(=14\%+28\%+18\%=60\%\), so left \(=40\%\) of the income
\(\frac{1}{4}\) of the remainder \(=\frac{1}{4}\times40\%=10\%\) of the income \(=\) ₹5120
Income \(=5120\times10=\) ₹51,200
Spent on electricity bills \(=14\%\) of 51,200 \(=\) ₹7168
