a) 3 hours

b) 4 hours

c) 5 hours

d) 6 hours

e) None of these

a) 11 kmph

b) 6 kmph

c) 8 kmph

d) 9 kmph

e) 7 kmph

Q.8) A man finds that he can row 12km with the stream in the same time as 6 km against the stream. He can row to a place 84 km distance and come back in 10 1/2 hours. The rate of the stream is?

a) 3 km/hr

b) 2.5 km/hr

c)  4 km/hr

d) 5 km/hr

e) 6 km/hr

Q.9) A boat goes 40 km in 4 hours along the stream and 27 km in 3 hours against the stream. Speed of the Stream is,

a) 1 kmph

b) 1.5 kmph

c) 0.5 kmph

d) 2 kmph

e) 3 kmph

Q.10) Ratio of speed of boat to speed of stream is 7:5; find the ratio of upstream time to downstream time to cover a certain distance?

a) 5:7

b) 3:2

c) 6:1

d) Cannot be determined

e) None of these

Explanations:

Q.1) b

The series is,

×2+22, ×3+32, ×4+42, ×5+52, ×6+62,

Hence 2566 is the wrong number.

Q.2) d

The difference is,

25    23    21    19    17

Hence 118 is the wrong number.

Q.3) d

The series is,

×0.5+1, ×1+2, ×2+3, ×4+4, ×8+5

Hence 1634 is the wrong number.

Q.4) b

The series is,

52+5, 152+15, 252+25, 352+35, 452+45, 552+55,

Hence 1280 is the wrong number.

Q.5) b

The series is,

×2+10, ×3+20, ×4+30, ×5+40, ×6+50

Hence 234 is the wrong number.

Q.6) b

Q.7) c

Ratio of time taken  (downstream and upstream) =  1: 3

Ratio of speeds (downstream and upstream) = 3: 1

Speed of boat in still water

= ((3+1)/(3-1) ) x 8 = 16 km/hr

Speed of boat upstream = 16-8 = 8km/hr

Q.8) e

Downstream speed

Upstream speed

X =0.5

Therefore,

Downstream speed = 24 kmph

Upstream speed = 12 kmph

Hence, speed of stream= ½(24-12) = 6km/hr

Q.9) c
