Question
A boat can travel at a speed of 15 km/h in still water.
If the speed of the current is 3 km/h, how long will it take to travel 24 km upstream?Solution
Effective speed upstream = Speed in still water - Speed of current = 15 - 3 = 12 km/h. Time = Distance / Speed = 24 / 12 = 2 hours. Answer: b) 2 hours.
What value should come in the place of (?) in the following questions?
70% of 240 + 75% of ? = 45 * 55 Γ· 5
(33 + 6.25% of 4096) = ? + 2 Γ 119
What will come in the place of question mark (?) in the given expression?
65% of 900 - 45% of 600 = ? X 3Β
212.3 Γ 4414.7 Γ 4623.4 Γ 4845.85 = 462?
18/2 of 3/9 of 2/6 of 69690 = ?
Simplify the following questions and choose the correct option.
(84 Γ 3) Γ· 7 + (64 Γ· 8 Γ 5) β 19 = ?
7/11 × 1034 + 1(4/7) × 2401 = 1230 +?
(1520 - 1350) Γ· (550 β 500) = ?
What is the value of 7/9-11/12+12/16-1/8?
85% of 620 + ? % of 1082 = 4855
