Anubhav's income allocations are as follows:
The total percentage spent from his income is:
(14% + 28% + 18%) = 60%
This means that he has 40% of his income remaining. Let's denote Anubhav's total income as X. The remaining amount is 0.4X.
We know that 1/4 of the remaining amount is Rs. 5120:
0.25 × 0.4X = 5120
Solving for X:
\(0.1X = 5120\)
\(X = \frac {5120}{0.1}\)
\(X = 51200\)
Now, to find the amount spent on electricity bills, which is 14% of his income:
Electricity bills = 14% of 51200
Electricity bills = \(0.14 × 51200\)
Electricity bills = Rs. \(7168\)
According to the question, the amount spent on electricity bills is Rs. 7160, which means there may have been a slight discrepancy in the question options. Based on calculations, the closest correct answer should indeed be Rs. 7160.
