**Here is the Quiz for IBPS PO Pre 2018.**

1).Train A travelling at 126 km/hr speed, completely crosses Train B in 9 seconds. Train B is half the length of Train A and is travelling at a speed of 90 km/hr in the opposite direction (towards Train A). How much will Train A take to cross a platform of length 690 metres ?

(a) 28 seconds

(b) 32 seconds

(c) 25 seconds

(d) 30 seconds

(e) 35 seconds

2) A streamer takes one hour more to go 48 km upstream than the time to go 60 km downstream. If the steamer takes equal time to cover 30 km downstream and 18 km upstream then find the ratio of the speed of the boat in still water and the speed of the stream.

(a)16kmph, 4kmph

(b)12kmph, 3 kmph

(c)14 kmph, 4 kmph

(d)12 kmph, 4 kmph

(e)none of these

3) A tank has three pipes. The first pipe can fill

(a) 3 hours

(b) 4 hours

(c) 5 hours

(d) 6 hours

(e)none of these

(b) 50 minutes

(c) 60 minutes

(d) 75 minutes

(e) None of these

5)A shopkeeper sold 12 cameras at a profit of 20% and 8 cameras at a profit of 10%. If he sold all the 20 cameras at a profit of 15%, then his profit would have been reduced by Rs 36. What is the cost price of each camera?

(a) 100

(b) 150

(c) 180

(d) 220

(e) Rs 16

Solutions :

1.(d); Length of train A

Length of train B

2. (a); Ratio of upstream to downstream speed =

Upstream and downstream speed = 20, 12 kmph

Speed of stream and water = 16, 4 kmph

3.(b); Let the 3rd pipe can empty full tank in

4.(b); Let usual speed

St =

5. (c); Let the cost price of cameras is c

3c = P – 36

3c = 3.2c – 36

36 = 0.2c

c = 180
