Directions (1-5): What will come in place of question mark (?) in the following questions (you are not expected to find exact value)?
Q1. 549.95 – 440.01 + 39.99 × 10.98 = ?
Q4. 299.02 ÷ 22.99 + 7359.99 ÷ 31.97 = ?
Q6. A man can row 30 km upstream and 44 km downstream in 10 hrs. Also, he can row 40 km upstream and 55 km downstream in 13 hrs. find the rate of the current and the speed of the man in still water.
Q7. A boat travels upstream from B to A and downstream from A to B in 3 hrs. If the speed of the boat in still water is 9 km/hr and the speed of the current is 3 km/hr, then find the distance between A and B is
Q8. A man can row at 6 km/hr in still water. If the speed of the current is 2 km/hr, he takes 3 hrs more in upstream than in the downstream to cover the same distance. The distance is
Q9. A man can row at 5 km/hr in still water. If the river is running at 1 km/hr, it takes him 75 min to row to a place and comes back. How far is the place?
Q10. A motor boat can travel at 10 km/hr in still water. It travelled 91 km downstream in a river and then returned to the initial point, taking altogether 20 hrs. Find the rate of the flow of the river
Q11. Ratio of speed of a boat in upstream to in downstream is 11 : 14. If boat travel 12 km in upstream and 28 km downstream in 2 hour then find the speed of stream is what percent of speed of boat in downstream.
Q12. A man can swim at 45 m/min in still water and he swims 250m against the current and 250 m with the current respectively. If the total time taken by man is 20 min, what is the speed of the current?
Q13. A boatman can row his boat at 14 km/h in still water. He rows from a point A to B upstream and returns from B to A downstream in a total time of 7 hours. If distance between A to B is 45 km, what is the speed of stream?
Q15. A boat travels from Point M to N. The distance between M to N is 12 km. It started from M and travels 4km in downstream in 15 min and covered the remaining distance between M and N in upstream. If the downstream speed of boat is twice as high as the upstream speed of boat. Find the average speed of the boat for the journey from M to N ?
