Question 9

Which of the following is the only movable bone in the skull of man?

Question 10

Question 11

A person rows a distance of

km upstream in

hours and a distance of 13 km downstream in 2 hours. How much time (in hours) will the person take to row a distance of 90 km in still water?

Question 12

A steamer has to travel from port A to port B. It goes downstream the river but due to some technical fault it has to return back to port A for the repair after covering half the distance. It stopped at A for 30 minutes and then again starts the journey to B with same speed as before. Due to this fault, it reaches B 2 hours 10 minutes late than the usual time. If it takes 20 units of fuel for 1 km and given the speed of steamer downstream is 15 kmph and the speed of stream is 3 kmph, then find the units of fuel used more than the usual?

Question 13

A man can row 2 km/h in still water. He takes thrice as much time to row upstream as to row downstream for the same distance. Find speed of water stream.

Question 14

A man can row 44 km in 11 hrs against the stream and the speed of current being 4 km/h. What time will be taken by him to row 65 km with the stream?

Question 15

A boat goes 4 km upstream and 4 km downstream in 1 hour. The same boat goes 5 km downstream and 3 km upstream in 55 minutes. What is the speed (in km/hr) of boat in still water?

Question 16

A motor boat, travelling at the same speed, can cover 25 km upstream and 39 km downstream in 8 hours. At the same speed, it can travel 35 km upstream and 52 km downstream in 11 hours. The speed of the stream is

Question 17

Time taken by a boat to cover 60 kms upstream is 3 hours. Calculate the time taken to travel same distance downstream by the boat if the speed of the boat in still water is 25 kmph.

Question 18

In a circular swimming pool, two swimmers A and B start swimming along the circumference of the pool from same point but in opposite directions. A swims downstream the water having rate 8kmph in still water and B having speed in still water equal to 3/4th of A. They meet at a point at 3/4th distance from A in 15 minutes. Find the radius of the pool. (take π = 22/7)

Question 19

A boat goes 20km downstream in 2 hours and it comes back the same distance upstream in 4 hours. What is the speed of boat in still water?

Question 20

The ratio of the downstream speed of a boat to the upstream speed is 40:7. If the boat goes somewhere along the flow of the river in 5 hours, how long will it take to travel the same distance in the against the flow of river?
