Percentage Practice Test 5 with solutions

20% = 800
∴ $100\%=\frac{800}{20}\times 100=\mathrm{Rs}.4000$
Anil's expenditure on food and transport $=\frac{50}{100}\times 4000$ = Rs. 2000
Remaining amount = 4000 – 2000 = Rs. 2000
Hence, his monthly savings $=\frac{1}{2}\times 2000$ = Rs. 1000
Then, his annual savings = 12 × Rs. 1000 = Rs. 12000
