Option C

Solution:

Distances upstream:

Monday = 18/100 * 150 = 27 km, Tuesday = 12/100 * 150 = 18 km.

Wednesday = 39 km, Thursday = 45 km, Friday = 21 km

Similarly Distances downstream:

Monday = 27 km, Tuesday = 45 km. Wednesday = 18 km, Thursday = 36 km,

Friday = 54 km

Let speed of still water upstream on Friday = x, then downstream on Thursday

= (10-x)

Now

21/(x-3) = 36/[(10-x)+2.5)]

Solve, x = 6.5

So required ratio is 3.5 : 6.5 = 7 : 13

2.View Answer

Option B

Solution:

speeds – 4x and 5x

So on Monday

27/(4x-3) + 27/(5x+3) = 9/2

Solve, x = 3

So downstream speed = 5x = 15 km/hr

3.View Answer

Option B

Solution:

8x and 3x, Also 8x – 3x = 5

So x = 1, speeds are 8 and 3 km/hr

So for Tuesday

18/(3-b) + 45/(8+b) = 14

Solve, b = 1 km/hr

4.View Answer

Option D

Solution:

On Wednesday

39/(4x-2) – 18/(5x+2) = 10

Solve

Solve, x = 2 km/hr

So required distance :

39/(8-2) + 18/(10+2) = 8 hours

5.View Answer

Option D

Solution:

Let speed of still water upstream on Thursday = x, then downstream on Friday

= (11-x)

Now

45/(x-2.5) – 54/[(11-x)+3)] = 12

15/(x-2.5) – 18/(14-x) = 4

The time is integral value, so by putting values higher than 2.5, x can be found

x = 5

So required ratio is 5 : 6
