Question
Select the correct combination of mathematical signs to
sequentially replace the * signs and balance the given equation. 11 * 7 * 345 * 5 * 31 = 115Solution
11 * 7 * 345 * 5 * 31 11 × 7 + 345 ÷ 5 − 31 77 + 69 - 31 146 - 31 = 115

- A motorboat covers 96 km downstream in 4 hours. Coming back upstream over the same distance, it takes 8 hours longer than the downstream time. Find the spe...
If the sum of upstream and downstream speed is 30 km/hr and the speed of the current is 6 km/hr. Then find time taken to cover 84 km in downward?
Speed of boat is 25 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 90 km downstream?
The speed of a boat in still water is 6 km/hr more than that of the current. The time taken by the boat to cover 875 km downstream is 17.5 hours. Find t...
