Speed of boat ‘A’ in still water = 120/12 = 10 km/hr Speed of boat ‘B’ in still water = 10 × (4/5) = 8 km/hr Downstream speed of boat ‘B’ = 8 + 3 = 11 km/hr Time taken by boat ‘B’ to cover 264 km in downstream = 264/11 = 24 hours
8(3/4) + 5(1/6) – 4(3/4) = ?
20 ×33 + 12 × 23 - 40 ÷ 15-1 + ? = 50
(750 / 15 × 15 + 152 + 20% of 125) = ?3
√ (12+√ (12+√ (12+ ⋯ ∞ ))
(60 × 8 ÷ 10) × 5 = ?
