Question
A boat moves with a downstream speed that is 8 km/hr more
than its upstream speed. If the boat’s speed in still water exceeds the current’s speed by 12 km/hr, calculate the downstream speed of the boat.Solution
ATQ,
Speed of the current = 8 / 2 = 4 km/hr
Speed of the boat in still water = 4 + 12 = 16 km/hr
Downstream speed of the boat = 16 + 4 = 20 km/hr
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
(4.89)2 + √144.35 - √121.25 = ?
?% of 309.99 = 40.01% of 249.99 + 295.98% of 49.99
The greatest number that will divide 398,436, and 542 leaving 7, 11, and 15 as remainders, respectively, is:
54.8% of 800 - √(?) = 33.98% of 400 – 12.42% of 300
(√4623.9 + √484.2) – √2303.97 ÷ √1296.4 × √35.98 ÷ √15.99 = ?
[{(√785) % of 449.85}/(35.89 × 7.14 + 849.89 ÷ 5.12 + 199.78% of 41.09)] = ( 1/? )
