Dear Readers,
We have started the 56 days Study Plan for IBPS PO Prelims. This study plan is to efficiently utilise time and hard work to channelise it towards smart work. From now quizzes on Bankersadda will be according to the given study plan and this will help you prepare important topics in limited time.
Today is DAY 37 of the study plan and in Quantitative Aptitude today’s chapter is Practice of 8-10 Chapters (Time & Distance And Boat & Streams)
Q1. A boat goes 24 km upstream and 28 km downstream in 6 hours. It goes 30 km upstream and 21 km downstream in 6 hours and 30 minutes. The speed of the stream is:

(b) 5 km/h
(c) 4 km/h
(d) 6 km/h
(e) None of these
Q2. A train passes two bridges 104 m and 194 m long in 12 seconds and 18 seconds respectively. Find the speed of the train.

Q3. In nut and bolts factory, one machine produces only nuts at the rate of 100 nuts per minute and need to be cleaned for 5 minutes after production of 1000 nuts. Another machine produces only bolts at the rate of 75 bolts per minute and need to be cleaned for 10 minutes after production of every 1500 bolts.

(e) None of these
Q5. A leak was found in a ship when it was 77 km from the shore. It was found that the leak admits 2.25 tonnes of water in 5.5 minutes. 92 tonnes will suffice to sink the ship.

(c) 7.5 hrs
(d) 8.5 hrs
(e) None of these
Q10. In a race of 800 m, L beats M by 45 seconds and beats N by 150 m. If M and N run a 800 m race, M beats N by 45 seconds. Find the time taken (in seconds) by M to run the race.
(e) None of these
Q11. Two trains T_1 and T_2 start moving towards each other from two station, 400 kms apart with seeds 60 and 40 km per hour respectively. At the same time a bird sitting on the engine of the first train starts flying towards second train, it touches the engine of second train and comes back with the same speed, again touches the engine of first train and returns to second train and so on till the trains collide. If the speed on the bird in first direction is 150 kmph and in the opposite direction it is 60 kmph. Calculate distance travelled by the bird in the first direction?

(b) 300 kms
(c) 200 kms
(d) 280 kms
(e) None of these
