Select the correct combination of mathematical signs that can sequentially replace the ‘*’ signs and balance the given equation.
18 * 6 * 63* 9 * 56 = 59
18 × 6 + 63 ÷ 9 – 56 = 59 18 × 6 + 7 – 56 = 59 108 + 7 – 56 = 59 115 – 56 = 59 59 = 59
A takes 3 hours more while swimming upstream than downstream. His speed in still water is 12 km/hr. The speed of stream is 4 km/hr. What is the distance?
Ratio of downstream and upstream speed of a boat is 5:2. If the speed of stream is 3 km/h, find the distance travelled by boat in downstream in 2 hours.
Motor boat covers a certain distance downstream in 5 hours. It covers the same distance upstream in 7(1/2) hour. If the speed of the water is 4.5 km/hr,...
Find the total distance covered by boat in still water in 8 hours if the speed of boat in upstream and in downstream is 10 km/h and 15 km/h respectively?
A boat running downstream covers a distance of 42 km in 6 hrs and covering the same distance upstream in 14 hrs. What is the speed of a boat in still wa...
A boat running downstream covers a distance of 24 km in 3 hrs while it covers the same distance upstream in 6 hrs. Then speed of the boat in still water is
A man can row one quarters of a kilometer against the stream in 30/4 minutes and return in 5/2 minutes. The speed of the man in still water is:
Speed of a boat in still water is 5 times more than the speed of stream. If boat covers 147 km in downstream in 7 hours, then find the time taken by the...
Speed of current is equal to 25% of speed of boat in still water. If the boat takes 14 hours to cover 140 km in still water, then find the time taken by...
Two boats X and Y start towards each other from two places, 155 km apart. Speed of the boat X and Y in still water are 14 km/hr and 17 km/hr respectivel...
