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

Q.10) c
