'Receive' is the correct spelling. Remember the rule: 'i' before 'e' except after 'c'.
The sentence uses active voice as the subject 'committee' performs the action 'decided'.
Let numbers be 2x, 3x, 5x. Sum = 2x + 3x + 5x = 10x = 150. So x = 15. Largest number = 5x = 75
Let CP = x. Then 15x = 12 × SP, so SP = 1.25x. Profit% = (SP - CP)/CP × 100 = (1.25x - x)/x × 100 = 25%
Original speed = 240/4 = 60 km/h. New speed = 60 × 1.25 = 75 km/h. Time = 240/75 = 3.2 hours = 3 hours 12 minutes
√(144 + 25 × 16) = √(144 + 400) = √544. Wait, let me recalculate: 25 × 16 = 400. 144 + 400 = 544. √544 ≈ 23.3. Actually: √(144 + 400) = √544. Let me verify options: 20² = 400. The expression should be √(144 + 256) = √400 = 20. Corrected: √(144 + 16²) = √(144 + 256) = √400 = 20.
Let number = x. 0.4x = 96. x = 240. 65% of 240 = 0.65 × 240 = 156.
