Option 1: 8%
Option 2: 15%
Option 3: 12%
Option 4: 10%
Correct Answer: 8%
Solution : Let the cost price be 100. Mark price is above 20% = 120 After discount of 10% = $\frac{90}{100}\times120$ Selling price = 108 Profit = Selling price – cost price = 108 – 100 = 8 Profit percentage = $\frac{\text{Profit}}{\text{Cost price}}\times 100$ = $\frac{8}{100}\times 100$

Option 1: 16 m
Option 2: 30 m
Option 3: 20 m
Option 4: 60 m
Correct Answer: 60 m
Solution : The speed of a bus = 108 km/hr = $108\times\frac{5}{18}$ m/sec = 30 m/sec Time = 2 seconds $\therefore$ Distance covered = speed × time = 30 × 2 = 60 m Hence, the correct answer is 60 m.
