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
Assume total income be P
Expenditure on Electricity 14% = 0.14P
Exp on rent 18% = 0.18P
Exp on shopping 28% = 0.28P
Total exp = (0.14+0.18+0.28)P = 0.6P
Savings = 0.4P
1/4th of savings = 5120
0.4P/4 = 5120
0.1P = 5120
P = 51200
Exp on Elect. Bill = 0.14P = 0.14*51200 = 7168
The correct answer is Option (2) → ₹7168
